Each shirt features Benjamin Franklin sporting a Rollie Fingers-like mustache. The Brotherly Game details the story behind the shirt design and the 'Stache Bash':
Through the mind of Sons of Ben member Jeremy Sharpe, and with the help of fellow members Chrissy and Mark Sakers, Sara Shepard, comes 'Stache Bash.' Sharpe decided to grow out his mustache one day and it immediately became a legend amongst the Sons of Ben. Long time friend of the Brotherly Game, Shaun Kreider, designed the shirt (his work can also be found on Broad Street Hockey and its own shirt store).â†µ
The shirts are sold for $15 apiece and all profits from the sales will benefit the Bernardine Center in Chester City, Pa. The design of the shirt can be seen by clicking the linked text here. A link to Bark Tees' pre-order form is found underneath the picture of the shirt design.
