Bronx Bombers Game Jersey is an insert set in 2003 Fleer Box Score. The cards feature game used jersey swatches of players on the New York Yankees. The cards were inserted into Bronx Bombers box sets (1 box set was inserted into each Hobby Box) at a rate of 1 per box or 9 per hot box. The Nick Johnson was limited to only 150 copies according to Fleer. The cards are number "X of 10 BB" on the card back, but card #2 was never released thus it is a 9-card set. It should be noted that Beckett's database incorrectly shows these cards numbered by player initials.
