I cannot find anything about it or any other players in this unique poster form anywhere online. The guy that has it told me he bought a St. Louis shop owners inventory 25 years ago. It definitely appears genuine, the aging and print quality both definitely checkout.
I'm kicking myself as I write this because I should probably buy it. The only thing stopping me is a pretty high asking price. If it was schoendienst I would in a heartbeat. It appears to be one of a kind.
Let me know your thoughts and expertise. Thank you.
