Grateful Dead "Steal Your Face" Logo First Stenciled

Was reading an interesting article/interview about LSD pioneer chemist Owsley "the Bear" Stanley
and hopped over to his site for further reading. In 1969, Stanley and
artist Bob Thomas worked out the Grateful Dead logo to mark the band's
equipment (here's his story). At first, it was just the three-colored lightening bolt, and was used as a stencil.

In the account, Stanley describes how it became a stencil:

"At the warehouse I told Bob the idea that I had, and he made a quick
sketch. A mutual friend, Ernie Fischbach, who was visiting with Bob,
said 'Give it to me, I'll show you an easy way to put it on the boxes.'
Whereupon he proceeded to cut holes in a couple of pieces of stencil
paper. One was a circular hole, about 5 1/2 inches in diameter, and the
other was a part of a circle 5 inches in diameter. But it was a half
circle with a jagged edge. Then he held the stencil to an amp and
sprayed a circle of white paint. Then with one side up, the red half
circle went on top of the dried white paint and after wiping off the
red and turning the stencil over, the blue was applied. This was the
first version, and we put it on to all our gear. It helped make it
easier to find our stuff in the crunch. I still have an old toolbox
with one of the stencils on it."
