While browsing Ebay, I found this beautiful ADPi pin from our Alpha Delta chapter at Colby College (active 1915-1974),
this. However, the item listed right below the pin was a Phi Mu pin,
here.
I never knew that Phi Mu's badge had a clapsed hand on it too. Interesting similarity...
EDITED TO SAY: I looked more closely at
www.phimu.org and realized their pin has a hand holding a heart, not clasped hands. Oops. Although they do share our love of lions (who'd win in a catfight, Alphie or Fidel? lol, jk).
