Mastery Mystery Episode 10 poster sells for 31K

A one-sheet lithograph for The Master Mystery Episode 10 sold on Friday for $31,000 at Poster Store Auction. This does not include the steep 31% buyers premium. It's unclear if this was the same poster that was sold by Haversat & Ewing in 2020.

The auction listing touted this as "only copy of this fabulous poster known to have survived," but this is not the case. There are at least two others in private hands. But it's a beauty and I think this might be a new record for a Master Mystery poster at auction.
