Unsigned N A Forsyth stereoview featuring a mammoth air compressor from a mine in Butte Montana. N. A. Forsyth was a photographer who operated a studio out of Butte, Montana, from 1904-1930, working for Underwood and Underwood and later Keystone View Company. Norman A. Forsyth was born on February 10, 1869 in Syracuse, New York. By 1902, Forsyth had relocated to Butte, Montana, and he began operating a photographic studio there in 1904 as the sole agent for Underwood and Underwood in Montana, selling views under his imprint as well. Forsyth captured stereo views of Butte city life and of copper mining and smelting at Butte and Anaconda. Nice clean card with good images.
