Cameras and Photographic Supplies, Sears, Roebuck & Co. (Chicago, IL), Form 410K, undated c. 1922, ~9"x12", 102pp
If Sears incremented their catalogs once per year, this catalog would be five years later than Catalog 410F and six years later than Catalog 410E. Since these are thought to be c. 1917 and c. 1916, respectively, Catalog 410K would be c. 1922.
