Excerpt from Duke Alumni Register These certificates, x 10 inches, have been mailed to all letter men whose names appear on our list. However, it has been impossible -to secure the names of all letter men, particularly for some of the earlier' years. So if you have not received your certificate, kindly fill O'ut the blank at the bottom of this page and mail to the Alumni Office at once and it will be sent promptly. It is the desire that all letter men have these certificates, so if you have not received yours it is simply because the name is not on the lists that have been compiled.
