MINNEAPOLIS AUTO SHOW MAR. 2-9, '07.

Pinback button promoting the Minneapolis Auto Show, 1907. An early 1 1/2" automotive related celluloid. There is some smudging of the blue ink in the white field in the center from the printing process, and a crimping irregularity at 7:00. Both imperfections detract little and are as made. No maker identified on this filled back pin.
