His "ex" being Carole Lombard, of course, but the "Moore" is that woman shown with William Powell, Grace Moore. Known as the "Tennessee Songbird" and a one-time star of the Metropolitan Opera, she was Columbia Pictures' version of Jeanette MacDonald, although she never quite had similar cinematic success. This image is from the Associated Press during the latter part of 1933, following the Lombard-Powell divorce that August, and while we can't show the snipe, according to the seller of this eBay, this is how it reads:
William Powell, screen actor, and Grace Moore, Opera singer and actress, are practicing a duet together, much to the amusement of Carole Lombard, screen actress and the former Mrs. Powell. Miss Moore, who has recently signed a long-term contract with Columbia Studios, was guest of honor recently after an operatic engagement in Los Angeles. All Hollywood turned out to pay her homage. Miss Moore’s first picture for Columbia has tentatively been entitled “The Love Child.” It will be made early next year. Miss Lombard’s most recent picture for Columbia was “Brief Moment.”
Moore became infamous for her temper; she was the type for whom the term "diva" was invented. Several months after this picture was taken, the Hollywood Reporter of June 13, 1934 printed this anecdote about an encounter Moore had with Lombard:
I'm sure the "menials" on the Columbia lot were thrilled to see Carole -- someone who stood up to bullies of either gender -- give Grace a taste of her own medicine.
The seller labels this 8" x 10" as "well-preserved," although a small piece of the upper-righthand corner is missing (I've cropped it out) and there also are "tiny creases." Nevertheless, it's in good condition.
This rare image has an initial bid of $20, with the auction scheduled to end at 3 a.m. (Eastern) June 1. If interested or curious, visit http://www.ebay.com/itm/Antique-Associated-Press-File-Photo-1933-Carol-Lombard-Unframed-8-x-10-/381267425522?pt=LH_DefaultDomain_0&hash=item58c54f38f2.
Moore, born in 1898, and Lombard each were nominated for Best Actress (Grace's came for "One Night of Love" in 1935) and shared a tragic fate, as both died in airline crashes. Moore's came on Jan. 26, 1947 in Copenhagen, a day after she had sung to an audience of 4,000 in the Danish capital. Lombard's old friend Gloria Swanson referred to their deaths in the film "Airport 1975."
