I have to toss in (because I was involved) the Southern Find from the mid-80's in which about 500 T213 series 2 cards and about 100 T213 series 3 cards made their way in to the hobby courtesy of a guy from Louisiana with a huge box of Coupon cards who rolled in to town. I managed to latch on to about 80 of the T213-3 cards (about 15 overprinted backs including 2 Cobbs with the OP backs), all in vg to ex-mt. Sadly they are long gone, before anyone asks. I sold them to Bill Mastro in the mid to late 80's (complete set -1) along with about 200 T-213-2s, but kept one nice Cobb OP back which I swapped about 5-6 years ago for a very nice E94 Wagner now in a PSA 4 holder. No T213-1s in the bunch. Any truly nice T213-3s (very, very tough and scarce) you see are probably from the find as Mastro broke up the set years ago. Probably my biggest regret as a collector...
