Hmm, actually, it looks like my copies of the card are subtlely different from one I found photos of. On the front, the text "Carl H. Lindner" on the front is less bold on mine, and the bottom corners of the photo aren't rounded. On the back, the margins are much narrower and more even, and there are a few minor differences in the text formatting. Also the signature on mine looks different -- maybe that card is geniunely signed unlike my printed-on signatures.
So maybe if this were added to the database, it'd be a two card set because of the variances, lol.
EDIT: Here's a scan of my copies of the card. (My dumb scanner clipped the side of the front card; I'll have to redo it later :P)
