LOS ANGELES (AP).- A Los Angeles gallery is taking head-on the dispute over garage-sale pictures that the owner says are the early work of Ansel Adams. The Duncan Miller Gallery is putting up 20 authentic prints by the renowned nature photographer in a brief show that opened Saturday. Next to those are prints from the collection of Rick Norsigian of Fresno, who said he bought the glass negatives for $45 at a garage sale, then had them authenticated as the lost work of Adams. Adams’ representatives dispute that Norsigian’s trove is the work of the photographer, who died in 1984. Next to the garage-sale find, the gallery will hang the work of photo-hobbyist Earl Brooks, who Adams’ family says is the real photographer behind Norsigian’s images.
