J.F.&Co. perfins on two of the six stamps. Perhaps W. Pohle got the envelope and perfin stamps from Johannsen Felix Co. drugstore in Mexico City. The cover is addressed to A.O. Tittmann in New York, a respected philatelist whose Sonora, Mexico Specialized Revolution Era collection was donated to the Smithsonian Postal Museum. The sender, W.Pohle, advertised in Meekels Weekly Stamp News, Vol. 30, June 17, 1916. He had a small 4 line ad, "50 Different Mexico, $2.00". The reverse of the cover advertises Tanglefoot, a sticky fly trap: "Guerra A Moscas" or War on Flies.
