The primary type of credential from the 1919 through 1931 period are celluloid and pin back button. Some celluloids from this period are blank on the back as seen on the 1926 Pitman while others have legal statements as seen on the 1928 Season Track Pass. The Whitehead & Hoag Co. of Newark New Jersey is one *known manufacturer of celluloid credentials as seen on the 1928 Season Track Pass. It is *uncertain who manufactured the other types of credentials from this period. Race day/race day official credentials are generally of the *celluloid or pin back button type while season and temporary track passes are generally *celluloid or thin cardboard.

The number 4 button on this race day credential is *believed to designate the 4th floor of the Pagoda which was for VIP's.
Note the Guest race day credentials have a red, white and blue ribbon
(the Pitman would've had one as well) while the track pass has a brown string in
correlation to the brown Wing & Wheel on the pass. Whether this difference is
the *case for all credentials is uncertain.
