Shake Shack, Center City at 2000 Sansom St., Philadelphia, is launching their newest product in coordination with local companies, La Columbe Coffee and Yards Brewery. Shake Shack is introducing, for a limited time, Yards Brewery's Coffee Stout Beer. $2.00 from every purchase will go to benefit the Philadelphia Mural Arts Program. Free commemorative posters featuring my original artwork will be given out starting at 3:30pm this Friday, January 9th. I will be at Shake Shack, Center City signing posters at the event. Hope to see you there!
