Grey Flannel was founded in 1989 in New York by Richard Russek and Andy Imperato. Grey Flannel, with their experience and expertise, has developed into the world's foremost authenticators and dealers of game-used jerseys. In 1994 GFC became the Official Appraisers and Authenticators for the Naismith Memorial Basketball Hall Of Fame. In 1998 GFC was hired by Sotheby's to authenticate the uniform collection of Barry Halper. Mr. Halper's collection rivaled that of the Baseball Hall of Fame in scope and was offered in auction during the early part of the summer of 1999.
