Maybe not a W575, maybe not a D383, but how about an E?
 

OK, let's open this up to discussion. I recently picked up a card that is generally thought to be either a W575 or a D383, but there is a curveball in the designation. This has been stamped on the back with a stamp that is identical at one point on with an E124 back except that this card has "Confectionery" on the back as determined by the "ery" that can be made out from the back of the card. The scan may seem light, but the card is that light on the back. As for the E124 reference, included are pictures to a card that has the same wording on the back from the line "Most prominent movie actors and actresses in the country" onward except for "Confectionery" on the card in question.

Has anyone seen another baseball card with the same stamp on the back?

I would say it is a Koester Bread card

Not sure, but sure that's a neat card. Nice one.

Thank you, John.

If the player is only in D383 then I personally would call it a D383 with a stamp on the back. If it is a player in the other W and E sets then I would call it a W575-1. I classify most back stamped, E121-like cards as W575 such as Burdick did. To each their own though.....

That same message can be found on the backs of American Caramel E123 Actors & Actresses, which more closely aligns with the issuance date of the Koester cards than does E124 (which were supposedly issued in 1923 per Google). I don't collect non-sports, and there seems to be a disagreement as to when E123s were first issued--Google has articles/ads for them represented as 1920, 1921 or 1922. The fronts of these actress cards are patterned after the ornate-framed E120s and not the square-framed e121s. They also have a blank-backed counterpart, W585, which could have been stamped.

It seems your card has a Koester's only subject, which dates it to late 1921. So it seems to line up with E123/W585. I’m having trouble picturing how a confectionery company employee stamping the backs of piles of W585s would somehow accidentally stamp a baseball card laying around. Maybe the same company also was privy to the Koester cards and had a separate stamp for those? Anyway, it would seem that the company would likely be located in the NYC area where Koester’s were distributed.

Todd, I know next to nothing about non-sports cards, but I have long believed that E123 refers to the Curtis Ireland Candy baseball cards. Is there a non-sports issue with this same ACC #?
