Since my first post about the General Dynamic Astronautics Time Capsule of 1963, we've learned that it was likely crushed when the building was torn down sometime in 1997. As noted in the comments, 201 copies were produced and distributed to major universities, which is where I happened upon the copy I now have in hand.

It makes you wonder just how many time capsules are destroyed each year when a building is torn down to make way for development of another kind.

The image above is from the second page of the 2063 A.D. book and shows the burying of the time capsule on July 13, 1963. I'll do my best to scan the entire book before returning it to the library.
