Chester T. Raymo (aged 24) on his graduation day from the University of Tennessee at Knoxville, 1933. He is accompanied by his sweetheart from across the street in Chattanooga, Margaret L. Dietzen (aged 20).
After scanning this negative, I found online a terrific digital archive of University of Tennessee yearbooks. Here I found the yearbook pages of all three of the Raymo brothers.
Arthur J. Raymo, graduated 1930
Chester T. Raymo, graduated 1933
Roger D. Raymo, graduated 1934
