The listing, 1981 Space Achievement Stamps has ended.
The 1981 Space Achievement block of 8 stamps in its normal configuration, with the 4 center space shuttle stamps, flanked by two smaller vertical pairs on each side.
This set is unused and was placed in a book the day it came out by my Father who bought a few full sheets.
The catalog numbering and the design of each stamp is as follows:
>>Top left stamp (#1912), Exploring the Moon, shows an astronaut on the moon.
>>Top stamp second from the left side (#1913), the Space Shuttle releasing its external tanks, before it goes into orbit. This shuttle stamp position is referred to as the UL position (upper left) in the block of 4 stamps.
>>Top stamp second from the right side (#1914), the Space Shuttle in orbit about to release a satellite from its cargo bay. This shuttle stamp position is referred to as the UR position (upper right) in the block of 4 stamps.
>>Top right stamp (#1915), understanding the sun, shows the Skylab manned space station.
>>Bottom left stamp (#1916), probing the planets, shows the Pioneer spacecraft near the planet Saturn.
>>Bottom stamp second from the left side (#1917), the launch of the Space Shuttle. This shuttle stamp position is referred to as the LL position (Lower left) in the block of 4 stamps.
>>Bottom stamp second from the right side (#1918), the Space Shuttle coming in for an Earth landing. This shuttle stamp position is referred to as the LR position (lower right) in the block of 4 stamps.
