Adams's first foray into making mural-sized photographs came in 1935, when he was asked by his employer at the time, the Yosemite Park & Curry Company, to undertake a series of murals of Yosemite for the San Diego Exposition of that year. He became an articulate spokesman for the form, writing articles such as 'Photo-Murals' for US Camera in November 1940, and including discussions of mural theory and practice in books such as his own The Print: Contact Printing and Enlarging of 1968. 'I was fascinated with the challenge of making a photographic print in grand scale,' Adams wrote in his autobiography. 'Many of my large-format Yosemite negatives took on a new resonance in mural-sized proportions' (Ansel Adams: An Autobiography, p. 187).
The present mammoth, mural-sized print was one of a series executed in the mid-1950s for the American Trust Company (later taken over by Wells Fargo Bank), for their offices on Montgomery Street between Washington and Clay Streets in San Francisco. These murals were printed in sections, by the Moulin Studios or General Graphics in San Francisco. The sections were so large that they were developed in mammoth trays, then mounted with wheat paste to Homasote board.
