World War II-era personal 'Good Luck' flag of a Japanese soldier, 33 x 28, featuring a printed red 'sun' in the center of the white cotton field. Two corners are reinforced with leather triangles. It was customary for family and friends of the Japanese soldier to sign these 'Good Luck Flags' before he went off to battle. When unfurled on the ground, they would be used by Japanese soldiers as warnings to friendly aircraft not to strike. In very good condition, with scattered staining and fraying to edges.
