Early Ansel Adams Photos Found at Garage Sale?

Collector Rick Norsigian and a team of experts are attempting to confirm that glass negatives found at a Fresno garage sale are the works of Ansel Adams.
And for a number of reasons, they’re already convinced.
The negatives are on 8.5”x6.5” dry plate glass, which is charactaristic of Adams’ work. One of the shots is virtually identical — down to the snow-capped mountains — to another confirmed Ansel Adams photo. And perhaps most convincing to Norsigian and his team: the handwriting on the sleeves containing the negatives has been authenticated as that of Adams’ wife.
