Original art piece done for the Grateful Dead in 1990 by Moon Otter. 
This piece features airbrushed color and Prismacolor pencils. This artwork was an original design for the Grateful Dead 25th Anniversary tour.
 
Moon originally created this piece with Steppenwolf in mind.  Obviously, it was not picked up by the group.  So, Moon who was not easily discouraged, presented this picture to Jerry who said, "This is perfect for the Dire Wolf song."   The Grateful Dead used it as one of their T-shirt designs. 
 
This piece is original and will not be editioned. 
Artwork comes as is, no frame included.  Frame seen in photos is digitally rendered to allow for representation of scale.
