The Alpha Chapter of Delta Kappa was installed at Buffalo State Teachers College, NY in 1920. The Initials inscribed upon the back are B.S.
This pin is exactly like the UW-Whitewater Delta Kappa Badges, except for the UW-W Badges had Chi Delta Chapter designation badge guards.
Secondly, I have found not one, but two Delta Kappa recognition pins. Both are identical, but purchased from two different vendors. The pin is a miniature replica of the Delta Kappa Coat of Arms. Great finds, for sure!
