Imperial German WWI Sanke Postcard 578 Oberleutnant Schleich Bavarian Pilot

Original Imperial German real photo portrait postcard (Sanke-Karte) Number 578 from the celebrated Wilhelm Sanke aviator series, depicting Oberleutnant Eduard Ritter von Schleich, the Bavarian fighter pilot known to history as Der schwarze Ritter (The Black Knight). The card is one of the most recognizable images of the Sanke series, produced and distributed by Postkartenvertrieb W. Sanke of Berlin North 37 during the latter portion of the First World War as part of the publisher's extended program of personality portrait postcards documenting the leading personalities of the Imperial German air service (Luftstreitkräfte).

The postcard measures approximately 3.5 by 5.5 inches (8.9 by 14 centimeters), the standard German real photo postcard format of the period, printed on period card stock with a high-contrast silver gelatin photographic image on the obverse. The obverse caption is printed at the upper left in white serif lettering reading Oberleutnant Schleich. The lower margin carries the publisher's imprint 578 / Postkartenvertrieb W. Sanke / Berlin N. 37 / Nachdruck wird gerichtlich verfolgt (Reproduction will be prosecuted). The reverse of the card is the standard Sanke divided-back postcard format with vertical and horizontal printed dividing lines for the address and message panels, and bears a small printed triangular publisher's stock identification mark at the upper right corner in red.

The portrait depicts Schleich at half-length, posed against a neutral studio backdrop, looking just past the camera in three-quarter profile to his right. He is wearing the field-grey officer's Schirmmütze with the Reichs cockade above and the Bavarian state cockade below, and a heavy field-grey officer's Mantel (overcoat) double-breasted with twin rows of brass buttons. The overcoat is fitted with a substantial dark fur collar (sheepskin or astrakhan-style lambswool) turned up against the throat in winter wear configuration, characteristic of the cold-weather flying dress favored by German aviators on the Western Front during the 1917 to 1918 winter campaigns. A 1914 Iron Cross Second Class ribbon is visible in the buttonhole of the left lapel, the only visible decoration in the photograph.

The historical context places the subject among the most distinguished personalities of Imperial German aviation. Eduard Ritter von Schleich (born 9 August 1888 in Munich, died 15 November 1947) entered the Imperial Bavarian service as an infantry officer with the 11th Bavarian Infantry Regiment prior to the war, transferred to the air service in 1915, and qualified as a fighter pilot in 1917. He achieved 35 confirmed aerial victories during the war, served successively with Jagdstaffel 21 and as commander of Jasta 32b and later Jasta 21 and Jasta 23, and earned the highest decorations available to a Bavarian officer of his rank. He was awarded the Royal Prussian Orden Pour le Mérite on 4 December 1917, and the Bavarian Military Order of Max Joseph (Militär-Max-Joseph-Orden), the highest military honor of the Kingdom of Bavaria, which conferred upon him the personal knighthood signified by the title Ritter von attached to his family name. The nickname Der schwarze Ritter derived from his practice of having his Albatros D.V fighter painted entirely black following the loss of a close friend in air combat, a distinctive personal marking that became associated with his unit during the latter portion of his combat service. He continued his military career after the war in the Bavarian Reichswehr, transferred into the Luftwaffe in the 1930s, and ended his service at the rank of Generalleutnant in 1945.

For the collector, Sanke-Karten represent one of the most defined and collected categories of Imperial German aviation ephemera. The Wilhelm Sanke series of personality portrait postcards encompasses approximately 270 individual cards depicting around 132 individual German aviators, produced between roughly 1915 and 1918 as part of the wartime patriotic postcard market. The series documents the leading personalities of the Imperial German air service across the full range of the war's duration, from the early Pour le Mérite recipients of 1916 such as Boelcke and Immelmann through the later aces of 1917 and 1918 including the Richthofen brothers, Udet, Göring, and Schleich himself. Cards depicting Pour le Mérite recipients carry particular collector interest within the series, and Schleich's cards are sought both for his individual reputation as the Schwarze Ritter and as representative examples of the Bavarian contingent within the otherwise predominantly Prussian aviator corps. The standard reference for the series is Charles Woolley's World War I German Aviators: The Sanke Cards (Schiffer Publishing, 2003), which documents this card as Number 578 in the established sequence.

Condition is honest and the card is offered with full disclosure of its handling history. The obverse photographic image remains crisp and high-contrast with strong tonal range, and the printed caption and publisher's imprint are clearly legible. Light edge wear and minor surface handling marks are present consistent with a century of storage. The reverse carries substantial period blue colored pencil scribbling across most of its surface, applied at some point after the card left the publisher and likely the work of a child handler in a family album. Underlying pencil writing in cursive is partially visible beneath the scribbling but is not readable. A small circled pencil notation reading 10 and a separate pencil notation reading 35 are present at the upper right, likely period dealer or collection inventory marks. The pencil markings are substantial enough to materially affect the visual appearance of the reverse but do not penetrate to the obverse image, which remains unaffected. The card is structurally sound with no tears, splits, creases, or losses, and has not been mailed.

The reverse condition issue is reflected in the offered price, which is set substantially below the level of clean examples of the same card. Collectors prioritizing the obverse photographic image and the subject identification will find this an accessible entry point into the Sanke aviator series, while those requiring pristine reverse condition should pass.
