Here in the Philadelphia area, Stephen Powers’ large-scale murals have been a colorful, entertaining and surprising presence since the 1990s. Although he’s currently based in Brooklyn, Powers has been spreading his personal brand of typographic signage murals around South America, Africa, Europe and the U.S.. This week the Princeton Architectural Press released a terrific retrospective of Powers’ vibrant, joyous work called “A Love Letter to the City”.
