Pizza museum a testament to American culture

It should have been enough that Brian Dwyer, a 28-year-old Philadelphia film student and drummer, was last year named the Guinness World Records holder of "the world's largest collection of pizza-related items." Yet obsession is a powerful thing. Dwyer's passion for all things pizza is so keen that he was able to persuade at least three other partners to create Pizza Brain — part pizza museum, part pizza restaurant — by purchasing and renovating two 19th-century buildings along Frankford Avenue's battered-but-burgeoning commercial corridor.
