Shuttle Tile (1.5x1.5x1") An unusually small, unflown tile that has its original hard, black cover on three sides. The tile is mounted on a 3.5x3.5" clear Lucite base with a descriptive plaque that reads: "HRSI tile from Orbiter Discovery". A minor chip does not detract. Scarce (Shuttle tiles can only be sold to citizens of the United States and cannot be exported). Ex. the actor Bruce Boxleitner collection.
