Rock your baby to sleep in this vintage (style) Springsteen baby onesie featuring a bandana clad state of New Jersey. Notice the details of the E Street piling within the word "built." Is it or is it not truly the house that Bruce built? Not often do you find a musician with as much chops as Mr. Springsteen, and no other son of Jersey celebrates his roots and wears them as a badge of honor than does the Boss, except maybe your boss baby.
