Three mysteries: Prints found at a flea market

Found: Sailor by the side of the road, Nov 1944

I love how the figure is extremely small in the landscape. There is no detail in the face in this print.

Joshua Tree

This small joshua tree photo is marked 6/29/27 on the back -- could that be right? The print is 2 1/4" by 1 1/2" (63mm x 40mm image area).

Dogs and coats

This dog photo cracks me up.
