Postcard featuring an illustration of the USS Niagara, the relief flagship of Commodore Oliver Perry during the Battle of Lake Erie, 1813. The illustration centers the USS Niagara, a wooden snow-brig with two masts, sailing in an open body of water. Her sails are furled and there are several nautical flags flying from her lines. Near the bow of the Niagara is a flag with the text "Don't Give Up the Ship", the last words of Captain James Lawrence and the motto of the ship with his namesake, the USS Lawrence, which served as Perry's first flagship until it sunk during the Battle of Lake Erie as Perry refused to surrender it to the British. Behind the Niagara is a gradient yellow, orange, and blue sky with white clouds. On the back of the card is a message from William J. Aicklen to Isaac H. Kempner discussing a meeting he had in New York and a visit with some friends on his way back to Houston.
