Another single page flyer  from Walkup's Air Brush Mfg. Co. The "eye" was airbrushed at the fair and were handed out to visitors. The idea was to acquaint people with the relatively new air brush and it's speed and ease of use. Unfortunately for Walkup, Thayer & Chandler were showing they're new internal mix air brush that  gave better results and was much simpler to use. The Thayer& Chandler was a derivative of Charles Burdick's original internal mix airbrush with refinements made by O.C.Wold, a foreman with Thayer & Chandler at the time. After the 1893 Exposition, Walkup's Air Brush Mfg. Co. was on the wane with competition from Thayer & Chandler. A  few years  after the turn of the century, Wold and another former T&C employee, Jens Paasche joined the fray along with other smaller companies like Ideal.
