I've found two photographs that I need information about. One is a picture of HALF DOME in YOSEMITE, the other is a meadow scene apparently also in the SIERRA NEVADA'S. The only information that I have is the meadow scene was apparently sold at a stationery shop in New Rochelle, N.Y. that is no longer in business. The only reference that I have for a possible date is a newspaper advertisement mentioning the stationer July 7 1922. The photos could pre date ANSEL ADAMS photo oh HALF DOME. Does anyone know a photographic historian who could date the pictures?
