RESTORATION OF DOCUMENT FROM SPACE MEMORABILIA COLLECTION

One of the few official NASA documents that were flown to the Moon on board of Apollo 12 mission and signed by Lunar Module Pilot Alan L. Bean.

Over the years this document printed on extremely thin velum which was treated and sterilized by NASA prior to the mission launch, began to display slight warping of the surface, exhibited minor tears and showed signs of discoloration.

The document was carefully cleaned and deacidfied to prevent further chemical deterioration. The tears were patched with an archival pH neutral compound and was flattened to reduce the appearance of warping.
