If Post Secret took over the streets of Philadelphia, covering The City of Brotherly Love with gorgeous murals featuring twee, romantic exclamations, you'd have A Love Letter For You, a project by Stephen Powers.

Quite possibly the prettiest graffiti ever, we can only hope no hoodlums smear cheesesteaks all over the walls (not a metaphor). There's only room for one kind of cheesy around here (honestly, though: this is beautiful)!
