The LDS church is downplaying an image (right) that some think may be the only known photograph of Mormon Church founder Joseph Smith.

"On the basis of available evidence it is not possible to confirm that the image is, in fact, of Joseph Smith," says a LDS Church statement.

But upon study, other historians of the American West speculate that the photograph is actually of William "Billy the Kid" Bonney (below) after detox at Sundance's Cirque Lodge treatment center. Contemporary accounts say the mystery photo is from a cover shoot for an early GQ.
