Photographic Specialties, A. C. Hayden & Co. (Brockton, MA), undated c. 1911, ~4¼"x5½", 16pp
This thin, 16 page catalog is undated, but A. C. Hayden advertised in Camera in 1910 and Field & Stream in 1911, so the catalog is likely c. 1911. The 16 pages include the un-numbered front and back covers, unless another cover is missing.
