Al C.risafulliLooks like the upper right and lower left corners of Ted's Feller are square. So I would imagine that the cards were first square, and then the corners were clipped, as the legend indicates.
Whether there was a warehouse "find" or not, I have no idea. That's what I've always heard, and always believed. I've also heard that the cards have been reprinted, and that reprints are often passed off as authentic.
Who knows? I'd imagine that if I had the cards since 1947, as Ted has, I'd be happy to know mine are real. But since I didn't have that luxury, I just won't buy any. That's one way for me to be sure.
