The colorful bus wraps don't address Amazon founder Jeff Bezos directly, and don't use the "Philadelphia Delivers" slogan developed for the city's charm offensive. Instead, the wraps extoll Philadelphia's vibrancy and livability, touting everything from bike trails to beer gardens. There are 30 slogans, all variations of "Philadelphia: City of Brotherly Love." There's "City of Foodie Love," "City of Mural Love," "City of Rooftop Love," etc., each with a corresponding image.
