This is a real photo postcard from the Benedicta Trunk photo album. A real photo postcard is one that used the standard photographic development process in a darkroom to print the postcard images. This particular one is an AZO postcard, which means it was printed on Kodak Professional AZO paper. The stamp box (where the stamp would go on the other side) can help us date the postcard. This one has four triangles (one in each corner) all pointing up, which was the type of stamp box used between 1904-1918.
I can’t help but notice the irony of this couple’s facial expressions against the photo prop. Bad date?
