What date (month and day) was the Travers Stakes run on in 1964?

Hello fitty,
After unsuccessfully trying to get the date online, I resorted to
placing a call to the Saratoga Springs Public Library. Their reference
department was most helpful. In their holdings is a pamphlet published
by the New York State Racing Commission, entitled The Travers Stakes:
Midsummer Derby. It records the date of the 1964 Travers as August 22.
If you have further questions, the library's telephone number is (518)
584-7860.
I might also recommend the website of the National Museum of Racing
and Hall of Fame in Saratoga Springs: www.racingmuseum.org.
All the best,
