Trying to figure out what this is. There are staple holes on the left - perhaps it was removed from a magazine? Blank back, measures 7 x 9.75.

Looks like a supplement of some kind...or m101?

Thank you very much!

Happy to be of assistance! I think it is cool, and I have only ever seen a WaJo, but I am not sure how much demand there is.

Thank you very much!

One of those was just auctioned off about a week ago, but I can't remember which auction.
