What does the g in Green Bay Packers stand for?

The Packers were founded in 1919 by Curley Lambeau and George Calhoun of the Green Bay Press-Gazette. Lambeau asked his employer, the Indian Packing Company, for money to buy uniforms. They gave him $500 on the condition that the team be named after the company. Lambeau named the team the 'Packers'.
