I'm not a photo expert. I'm not 100% sure what type of photo they are. Definitely photo card types.
Berlin Germany Cityscapes. Some cool automobiles and buildings in these.
Best guess is the type dictates they're from around 1920.
Smaller...approx 3.5 x 2.25"
Good antique condition
Black and white with a touch of sepia tone
