I just wanted to provide some pictures of a recent (also on ebay) Koesters Bread find. These were not sheet cut but were factory cut as seen in the scans...
From this grouping the Casey Stengel and Ed Brown are the only 2 that are "exclusive" cards thoretically distributed only with Koesters. The other 4 are all players that were produced with at least the E121 American Caramel set if not several other brand backs. I see no difference between these four and other W575-1 cards.
Also, of all the Koesters exclusive cards the Stengel shown here has been one of the most elusive to me over the years, so I am really excited to add him to the collection. He would definitely (in my opinion) be the second highest demand Koesters card (other than the Jesse Burkett).
Anyways, I just wanted to share another mini Koesters find.
