I've always loved this 1970's postcard which reproduces a Bruce Springsteen concert poster. It appears to be one of Eric Meola's classic shots from the same photo session that produced the Born to Run cover – with the addition of the “Wild and Innocent” on the back of the jacket (a reference to the Boss' previous album The Wild, the Innocent & the E Street Shuffle) and a pair of baseball boots slung over the end of his guitar.
It advertises a forthcoming gig at New York venue The Bottom Line and the album Born to Run. Born to Run was Springsteen's third album and was released in 1975. It was ranked #18 on the Rolling Stone 500 Greatest Albums of All Time.
