Custom on field style jersey. Everything is sewn on, size XL. Hand-signed in black Sharpie pen by John Rocker. When signing, Rocker inscribed "F*ck NY" along with his signature. During an interview, he spoke of his opinion of the Mets and their fans: Nowhere else in the country do people spit at you, throw bottles at you, throw quarters at you, throw batteries at you and say, "Hey, I did your mother last night--she's a whore." I talked about what degenerates they were and they proved me right.This autograph is certified by Beckett Authentication Services (BAS) Witness Certification.
