View art created by Richard Biffle - ALBUM COVERS & POSTERS.

Renowned Grateful Dead poster artist Richard Biffle began his career by selling art out of his van while following the band around the country.

Now, more than 20 years later, most of his works have sold out and are in high demand.

In addition to the Dead, the rock poster artist -- who recently moved to Nederland -- has worked closely with artists such as The Black Crowes, Carlos Santana, The Doobie Brothers and Yonder Mountain String Band to create works of art that have morphed into valuable, vintage pieces.

"I've had a lot of fun in the rock 'n' roll business," Biffle said. "It's a seedy business and it can get nasty, but it's the nature of the beast. It has been a fascinating world."
