Scovill's Photo. Series No. 20, Dry Plate Making for Amateurs, George L. Sinclair, Scovill Mfg. Co. (New York, NY), dated 1886, ~5 ½"x8 ½", 28pp & 30pp catalog
According to its title page, this small volume is a reprint of several articles that appeared in The Photographic Times, a periodical published monthly by Scovill Mfg. Co. The 30-page catalog that appears at the end also appears at the end of every other volume of Scovill's Photographic Series. There are staple holes near the center binding; apparently the book was originally softbound, then professionally rebound with these stiff cardboard ends with the wonderfully saturated color. The Scovill-bound No. 12 is 5 ½x8 ½", so it appears that ½" was trimmed during the binding process.
