2-1/16" button likely missing a backpaper and with rather heavy but not damaging oxidation on the metal back. The front celluloid is just a hair concave rather than convex. Pictured are a pair of fire horses and eight firemen with text at center naming the brewing company plus "Compliments Of" while the outer rim reads "Central District Firemen's Association/August 24-25-1904 Windber, Pa." Bottom edge has name of maker Pulver of Rochester. Overall VF with totally clean celluloid and displaying Exc. Only example we've seen.
