That is odd. As far as I know, our pins never looked like that! I see you (?) posted something in the Sisters Only section of the Sigma Kappa web site-I think I'll keep my eye out for any responses there! I'm dying to know where its from!
There was no response to the thread you made on the bulletin board Jen but another girl made a later thread addressing the same pin. Here is what Julia (legal counsel) said:
"The badge with the odd shape is not a badge of Sigma Kappa Sorority, as our badges have always been triangular in shape. It is probably the badge of a local organization named Sigma Kappa, but the seller doesn't have that information. "
