[1880nonsports]

but after seeing the last picture from the back - simply paper embossing/debossing done with a mold and pressing. There are some 1910's postcards that were done in that style featuring baseball and a myriad of other subjects. The FRONT does have a more interesting "look" than the generic examples usually encountered.
Similar production can be observed on a small set of 1890's store cabinets featuring women (what else :-)) where certain elements "puff-out" and many early cigarbox labels were embossed. Unsure if it was a different process but same idea. I'll try and post a pic. of a low grade store card exhibiting the same effect I have somewhere......

The best part of your example is that it does something for you. Not a lot of cash value but finding something you love is priceless.

BTW - It's PRINTED not a photograph.
