Space Shuttle flown artifact acrylic (4x4'') #3

Space Shuttle acrylic with space flown artifact 10x10cm (4x4''). It's 1cm thick (0,4'')

The attached artifact (flown insulation from Space Shuttle) came from an auction and with authentic paperwork.

The artifact is attached to the acrylic from behind (not encapsuled). We strongly recommend not to try to remove the artifact.

None of the artifacts come from the ill-fated flight STS-107 but were removed during earlier maintenance.
