I came across this on Pintrest. Unfortunately it looks like they changed the pickup but the guitar looks to be in great shape.

That's the same guitar as the one in this thread:

A 2004 post from Susan talks about them.

There were other guitars made at Alembic for Jerry, of the first dozen instruments made, 5 were guitars for Jerry. He wanted a guitar that had the smallest body imaginable, I called them peanut guitars. Those guitars eventually evolved into the Guitar that later became known as Wolf. BTW we currently have a peanut guitar number 6 made for Jerry that we are refurbishing for sale. 

Thanks Doug!
