A color lithograph patriotic fan sample print, likely created between 1937 and 1941 during the Second Sino-Japanese War (1937-1945)*, extolling the brave warriors of the suicide tank squads.
The print carries the sample catalog number そ印 參百五拾參號 (so in sanbyaku go jū san gō ). These numbered fan prints (uchiwa-e 団扇絵) were gathered into a sample book (uchiwa mihonchō 団扇見本帳, or uchiwa gachō 団扇画帖.) to show wholesale customers the range of available designs.
* Referred to in China as the "War of Resistance Against Japan."
