- Indianapolis Motor Speedway Credentials -



*Please note: In order to preserve the picture clarity of these credentials, this page may take a while to load. Please be patient.

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.

Celluloid "Driver" & "Exclusive Concession". Note that the race is called the "Liberty Sweepstakes".

Usher Ribbon


This 1920 Pit Paddock credential is of the thin cardboard type as are the 1921 and 1922 Pit Paddock credentials below.


The pin back button portion of a 1921 season track pass. It would've been attached with a short ribbon like the 1920 season track pass above.


1922 Celluloid Season Track Passes


There are probably others, but this is the only year *known where a celluloid pin back type of credential was manufactured.

The manufacturer Whitehead & Hoag is represented on the back as "W. & H. Co. Newark NJ."



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.



The "4" is believed to be the same as the 1926 above.

This 1927 Information and the 1929, 1930 and 1931 Ticker Seller pin back buttons are the *largest credentials known measuring about 4".


A thin cardboard credential from the Hispano-Suiza - Stutz 24 hour race of April 18th, 1928.


The different color and number on these Pit pin back buttons may be to differentiate the *pit box number.

This Ticket Seller and the 1927 Information are also the largest *known pin back button credentials known measuring about 4".

One of the more unusual credentials issued by the Speedway.

Note that the top track pass is celluloid and the bottom two are of the thin cardboard type.



The track pass at left is celluloid while the one at right is paper.

Note the thin cardboard type "Fyr-Fyter" at right.


Note that the Race Day credentials above are celluloid and the ones below are pin back buttons. *Why some were done as celluloids and others as pin back buttons is uncertain.

Celluloid season track pass at left, thin cardboard temporary track pass at right.


** 1925 is the earliest known example of a number button on a Race Day Official Credential. The numbers (which can be on a button or printed on the credential), are beleived to designate a floor of the Pagoda. Most are found on "Guest" credentuials, but there are examples other than "Guest" with the #2 1946 "Pagoda Paddock" being one of them.

Credentials from 1919 through 1931 become easier to find although none can be considered an easy acquisition with the 1929 and 1930 celluloids the two most likely to be found. Any credential associated with a race team, such as Pit pin back buttons or Driver celluloids are generally tougher to come by and more desirable than one designated for Press, Concession etc..
