It's Carole Lombard p1202-641, taken sometime in 1933. We know this because the seller of this item noted the date stamped on the reverse of this is Nov. 7, 1933 (although the back of the photo, or any other information such as a snipe, isn't shown). The dress looks similar to one Carole wore in p1202-638...
The p1202-641 on sale measures 7.25" x 9.5" and is said to be in "Excellent Condition, no bends or creases." You can buy it for $99.99 straight up or for $17 monthly for six months.
