Question 1918 Polish Central Rescue Comm Poster
I received this poster (11.5 in x 15 in) as part of an estate from Chicago USA. I believe it is a WWI Polish Central Rescue Committee poster, and has a postage stamp style coupon glued on it, in the amount of "2 dol" . The drawing is signed " W T Benda" and shows a military unit advancing under the watch of a glowing Madonna and child. Does anyone know anything about these war stamp style posters or this one in particular?
