The image above is an American version of the German postcards from the late 19th and early 20th century. The postcard was found in the book Out of Time: Designs for the Twentieth-Century Future. The text on the left reads, "Compliments of Maher and Crosh Cutlery Co." while the text on the right reads, "Toledo, Ohio."
The image below is the German version of the postcard.
