These are funky pictures! One picture is the Poor Poet, the other is a picture of a town and there's a name on the building "Fiolenthul".
The image is chemically etched on the back of the glass(Not sure what the exact process is). On the back of the image it looks like a very thin sheet of black carbon paper.
They are both labeled Mobilair 1978, I'm assuming this is the company that did the reproductions, but I've been unable to find any information to verify.
The beveled wood frames are in good shape but need some paint touchup.
The pictures measure 14x14
(Please excuse the microwave in the back of the picture, I was trying to find a spot somewhere in the house without glare!)
