Here is a college fraternity established in 1914 with a credo that includes general community service. This image of a dapper suited gentleman with top hat and cane caught my attention. The list of "famous Sigmas" includes many sports figures you might just remember.
I don't know much about Phi Beta Sigma Fraternity, but their mission statement being one of service is definitely in line with my life statement of service to humanity. The suit alone is priceless.
