So this actually comes from an interesting place. There used to be a Libertarian group here on dA a LONG time ago. Over 4 and 1/2 years since someone last logged onto that account.
Anyway - this design was being used as their ID at their time of death. I decided to vectorize it and offer it as a resource.
