This photo was recently discovered in a photo album that used to belong to Paulita Maxwell, allegedly Billy's true love. Whereas mos photos in the album had some kind of identification, this one apparently had none. Although the face resembles Billy, the tie and neckwear seem more contemporary of the turn-of-the-century era.
