Stereoview photograph of a cog railway train at Mount Washington, New Hampshire, by S.F. Adams, circa late 1860s to 1870s. The view, entitled View on Mt. Wash’n Railway, N.H., shows cog railroad tracks running out of the foreground and turning to the left with a cog railroad locomotive and passenger car just beyond the corner. Bare mountain peaks form a backdrop for the scene. The stereoview is in very good condition with only minor wear and soiling. The photographs exhibit good or better tonal range and show good or better detail. A nice early Mount Washington Cog Railroad image!
