The reverse of this official U.S. Navy photograph identifies it as image No. 474, taken aboard the escort carrier USS Petrof Bay (CVE-80) on April 16, 1945, and prepared for the ship's Air Department. Stamped 'Confidential' and marked as not for publication by order of the Bureau of Aeronautics, this caption card illustrates the strict wartime controls placed on official Navy photography, much of which remained restricted from public view until long after the war's end.
