The precursor to the San Diego Comic-Con International, known as the Golden State Comic-Con, was first held at the U.S. Grant Hotel from August 1–3, 1970.

The hotel was originally built in 1922 by Ulysses S. Grant, Jr. (son of president Ulysses S. Grant) who named the hotel after his father. The hotel is now on the U.S. National Register for Historic Places (probably not for its role in comic history, but should be).
