I bought a Tubular Bells album back in the 70's and the center label on the record was Aerosmiths first album.
Dumb me didn't realize it might actually be worth something someday and ended up throwing it away.

A friend of mine also has that early Beatles album with the babies and meat on it and his copy had a big sticker covering the discontinued cover artwork. Apparently he totally devalued it cause he peeled the sticker off.
