A trade catalogue or sample card from 1890 issued by Charles H. Howell & Co. of Philadelphia, a paint firm, offered to paint buyers and dealers. The only picture is a circular trade mark stamp reading TRADE MARK, PHILA, U.S.A., with the initials C.H. and H.C. in four quadrants, which suggests a compact monogram emblem a designer could adapt for a vintage paint or hardware brand.
