It is believed due to an incident where someone was burned due to the high flammability of celluloid, a decision was made to eliminate celluloid and use a different material for credentials. 1932 is a transition year for credentials as the type changes from being primarily celluloid or pin back button to almost entirely cardboard/pasteboard with a few exceptions noted below. Race day/race day official are blank on the back from 1932 through 1934 but become two sided in 1935 with the same design on both sides. Season track passes are two sided with a design on one side and an information area to be filled in on the back. Temporary track passes *generally have a design on the front and at least *three paper tear off pages on the back. On some years the last page is either glued or has stuck to the back of the pass however, it is *believed that over time this has occured and these were not originally made like this. From 1936 through 1946, a small serial number appears on one side of all cardboard/pasteboard credentials. From 1938 through 1946, metal pit badge credentials were issued along with cardboard/pasteboard credentials. Please refer to the Badges page for more information regarding badges.
1932
The number 4 button on this race day credential is *believed to designate a private
grandstand box.

are those of 1934 and 1937.
1933
The large number 4 on the race day credential at left and those on the 1934 and

It is not certain what type of material was used to make the Ticket Seller
credential above, but it *may be of a medium to heavy paper similar to the
1936 Lap Scorer below.
1934
1935
The Newspaper Boys of America pin back button above is not believed to
be issued by the Speedway, but by the date, it was obviously used on race day.
1936
The race day/race day official Pit above is the *last known pin back button type issued by the Speedway.
The Lap Scorer ribbon above and the 1940 Gaurd ribbon below are believed to be *made of a medium to heavy paper.
As these are the only examples from pre World War II (there are examples after WWII), it is
*assumed that this type was used for other years prior to 1941.
