Here's a Carole Lombard-William Powell pic I've never seen before...and thanks to a snipe on the back, we know much more about it:
It appears to be from September 1933, a month after their divorce, at tennis matches in Los Angeles...and as the caption notes, they had been seeing quite a bit of each other after their split. (As we know, Carole didn't go to Reno for the divorce, but to Carson City -- http://carole-and-co.livejournal.com/277114.html.) There's a stamp on the back marked either 1933 or '38, and another from March 1984, not long after Powell's death at age 91.
This pic is available on eBay, but you don't have much time to get it -- the auction is set to end at 7:18 p.m. (Eastern), less than two hours after I write this. It measures 6" x 8" and is in good condition; the opening bid is $19.97. If interested, proceed ASAP to http://www.ebay.com/itm/161242298640?fe_1_1.
