View of U.S. Marine amphibious alligator tank. Label on back: "Like a battle-maddened antediluvian monster crashing its wallowing way out of a primeval swamp to get at its enemy is this 'alligator tank' of the United States Marines, proving that it can go anywhere, in a test amid the bayou-splashed Florida swamps where never another kind of battle-tank in the world could navigate without bogging down." Stamped on back: "Official photograph, U.S. Marine Corps." Handwritten on back: "Amphibious vehicles."
