Rick Norsigian purchased a box of 65 glass negatives 10 years ago at a yard sale in SoCal for $45 have been estimated to be worth at least $200 million.
These glass plate negatives were thought to have been lost long ago in a darkroom fire in 1937. Experts speculate that Adams somehow left them behind when teaching a photography glass in Pasadena in the 1940s.
