The Dancing Bears? 
Those, and the Dancing Skeletons were part of their "logo" during the day.
The stuffed "Grateful Dead Beanie Bears" came out in the 90's when the Beanie Bear craze was going.
My mid 20's sons are both deadheads, have college degrees, and love Ole Jerry. They both voted for President Bush and have W sticker on their cars.
Now they follow String Cheese, and Widespread.
By the way, what is up with the teddy bears? I was not that cool back in the 70's.
