The Signature Series T-shirt line started in 1990 as a means for musicians and artists to benefit charities of their choosing. Each artist donated an original piece of artwork which was reproduced on a limited edition T-shirt and sold at Hard Rock locations worldwide and online. Since its inception, sales from the innovative series have raised more than $6 million for a wide variety of causes.
