Skylab (SL-1) Flown Fragment of Space Station as Recovered in Australia, in Lucite Display.
 
Flown fragment of a Skylab oxygen supply tank recovered in Western Australia after the space station’s fiery reentry in 1979, approximately 1 x 1, encased in a pyramidal 3.25 x 4.5 x 3.25 block of Lucite with a Skylab insignia at the bottom. In fine condition.

On the bottom, it reads in full: "Skylab, America's first space station, was launched on May 14, 1973, from the Kennedy Space Center, Florida. After orbiting the Earth 34, 981 times and traveling almost 1 billion miles, the space station reentered the Earth's atmosphere on July 11, 1979. Discovered in Western Australia after surviving its fiery reentry, this historical Skylab fragment was authenticated by NASA."
