This is a postcard of the Battleship S. M. S. Rheinland. She was commissioned in 1910. Along with her three sister ships of the Nassau Klasse, she formed the I Battleship Squadron. She fought at the Battle of Jutland (Skagerrakschlacht) and suffered one hit from British gunfire. Interestingly, she had four turrets: one in the center afore-ships and one in the center astern, then two off-center on the port side, an interesting arrangement. She is depicted in profile from the port side, since she is in a harbor with small boats coming and going from her. The postcard was never mailed, but the technical details are printed in the upper left corner.
