Astronaut Autographs

I know they're worth something but do not know where to sell them that would OR ARE them.They the first man on the moon to the shuttle disaster in 1986.

Ask them to assess, then with an auction house.

Research on Ebay, even past auctions. This gives you the best estimate. Your best bet is to sell too.

Edit: Sotheby's does not sell this kind of photo.

Sell them on e-bay

I love them, but I doubt that could afford it.
