I like Greg Morris Cards a lot and have bought several cards from them via eBay, and I think they generally try to get it right, although they did list a batch of cards as "1969 Nabisco Team Flakes" that were actually cut-outs from a Sports Illustrated poster guide. Some of you will no doubt remember those posters and recall that many use the same photos as the Team Flakes cards... but not all! Also, on the Team Flakes cards, the logos are airbrushed out, but they're visible on the SI posters. I sent GMC an email about it, but I never heard back, and at least a few of them appear to have been sold. (I counted eight.) It's possible that they may have contacted the buyers and offered to cancel the sale, or maybe they didn't see my message at all. Who knows for sure?
Here's one of the Not-Quite Team Flakes cards:
