On the Beta Nu Zeta's new Alumni Assocation website, There is a pretty big section that includes information about the Evolution and Development of the Lamba Chi Alpha's Brother Badge as well as the Theta Kappa Nu's Badge.... It includes a nice Photo Gallery of different variations of the Badges....
This information could be used for a nice Kappa Session.... just an idea
