Hyatt's Bargains Catalogue Supplement of Specialties, Hyatt's Supply Co. (St. Louis, MO), undated c. 1913, ~5¾"x8", 12pp
This is a plain paper, bare list of used photographic equipment, mainly cameras and lenses. It is undated, but one of the used offerings, the Empire State No. 2 View Camera, was only made c. 1908-1913, so the list may date to c. 1913.
