C.S. Bok was a friend Mort Austin met at Centenary Collegiate Institute. Mort attended the Seminary only a year due to health or financial reasons, but C.S. Bok and Mort continued to correspond and visit each other for a number of years.
One of the many Austin postcards shows Chinatown in NYC, where Dr. Bok lived, according to the note on the back of the card. The card must have been sent in 1907 or later, as 1907 was the first year writing on the back of Postcards was allowed by the U.S. Post Office.
