(note a) The NASCAR Grand National Series (today known as the NASCAR Cup Series) had first visited the Chicagoland area in 1954, when a reported crowd of 6,000 watched a race at the suburban Santa Fe Speedway.

[3] This was the first NASCAR Grand National Series/NASCAR Cup Series race to be held in the city of Chicago.

[4] It is today regarded to have been the only NASCAR Cup Series race held at the Soldier Field.

The fourth, fifth, and sixth-place finishers (respectively: Speedy Thompson, Frank Mundy, and Buck Baker) all were racing for Carl Kiekhaefer's team,[10] which had dominated the 1956 Grand National Series season.

[16] Legend: The 1957 edition of Soldier Field's annual Chicago Park District Police Benevolent Association Gold Trophy Race (held on June 15, 1957) was sanctioned by NASCAR as a 50-lap short track race under the "NASCAR Grand National" banner.

[8] For reasons that are unclear, Soldier Field never held another NASCAR Cup Series race.
