Hope someone can help with this.
 

Thought I’d post this here to get a few more eyes on it. I picked this up in a auction a few months ago and haven’t had any luck identifying it. My guess is from the mid forties based on the Corporal Greenberg identifier. The card stock is a little thicker than a traditional card and they appear to be cut of a box/display. Any help you can provide would be greatly appreciated.
