Here’s an incredible item I can’t remember seeing before: a 1937 Goudey Thum Movies Uncut Seet featuring 300 individual views.
Richard Wolffers Auctions, Inc. offered this sheet in their December 1994 catalog. They noted a few faults, including a few sealed tears with tape, so they offered it as a VG item. The estimated value was $5000-6000.
I can’t really make out any players on the sheet, and I’ve never seen the inside of any booklets, and while there is a 1938 Goudey Big League Baseball Movies set (R326) with the same dimensions, I’ll take the catalog’s word that these are the photos from the 1937 set (R342). Let me know if you can confirm!
