Snapshot of a shirtless man on a motorcycle, U.S. Army Soldier (WWII, Harley Davidson?)

Playful snapshot of a shirtless man looking about to abscond on a motorcycle, ca. 1940s, 3.25 x 4.5 inches, Near Fine condition. Presumed to be a soldier on what appears to be laundry day, blankets and jackets hanging between the trees and two rifles propped against the trunks. Number stamp on back, no other identification. Uniforms and bike look like maybe WWII, Harley Davidson.
