This is a hard to find extra large paperweight by Cristal d'Albret (made in France) to commemorate the four U.S. Astronauts:  it is a white cameo depicting the images of Edwin Aldrin, Michael Collins, Neil Armstrong, and Alan Shepard on a translucent cobalt blue ground.  The top is a large round flat facet.  There are 8 round facets all the way around the groove-cut sides.  This was a limited edition done in 1971.  The original Cristal d'Albret sticker is on the bottom. Astronauts names are under each one and "NASA" is also stamped twice.  Diameter is 3 7/8" and 2" tall.  Includes original box. Like new condition.
