Crack dealers seeking to expand their markets are using business cards and promoting their products, the New York Post reported Friday.

Dealers also are distributing fliers urging youngsters to "earn big bucks" by becoming "crack-er jack salesmen," the paper said."Their business cards say how good (their drugs) are and that they want a nice quick transaction," said Lt. Michael Geraghty, head of the Queens anti-crack unit.

The paper said dealers give out the cards after getting to know a customer, and that the card steers the buyer to the dealer's apartment or street corner.
