Artist Unknown Back Him Up! Mud splattered Canadian infantryman is pictured braving shot and shell as he faces a devastated no-man’s-land. The viewer is meant to look over his shoulder to see exactly what he faces. This is a surprisingly realistic look at the plight of a single World War I combatant who needs all the support that bonds can provide. Very rare. We have only seen this once in 40 years. 39×25 near mint, conservation backed.
