This is the third in a five-year commemoration series marking the 50th anniversary of World War II. Each year's souvenir sheet depicts a map and contains 10 stamps, each documenting key events of the corresponding period 50 years ago. The 1993 souvenir sheet and stamps highlight the following 1943 events and subjects: Allied forces battle German U-boats; military medics treat the wounded; Sicily attacked by Allied forces; B-24's hit Ploesti refineries; V-mail delivers letters from home; Italy invaded by Allies; bonds and stamps help war effort; "Willie and Joe" keep spirits high; Gold Stars mark World War II losses; and, Marines assault Tarawa. Each of the sheets includes a map depicting the location of the events noted on the stamps. The map on this sheet mistakenly shows Wake Island as being outside the rule of Japan, when it was actually Japanese territory in 1943.
