Apollo 11 Moon Landing - Unusual 2-D Dual-Image Mint Commemorative Sheet

This 1972 2-D sheet from Ajman commemorates the historic 1969 Apollo 11 moon landing. By tilting this remarkable sheet, the images on the stamp alternate between the command module entering the earth's orbit and the splashdown in the Pacific Ocean, while the image in the margin alternates between Neil Armstrong about to take the first step on the moon and the iconic image of Buzz Aldrin and the American flag. Sheet measures approx. 4" x 2". (Ajman Michel #Block 375)
