Google "Auburn Digital Library" and click on "browse collections". Then go to the Auburn Glomerata collection. They have every yearbook scanned from the very first Glom. You can "virtually" go through the Gloms of the early 50's to see if your dad is in the Athletics section. Most Gloms have team pictures. You can also look in the student pictures to see if he's there.
