I will be posting lots of Vulcan Gas Company posters here soon...created by Gilbert Shelton, Jim Franklin, Tony Bell, John Shelton, etc. from a collection the South Austin Museum of Popular Culture acquired from a rare book dealer in New Mexico...who was a grad student at UT when the Vulcan was operating...he collected them and put them away...they're in pristine condition.
I just posted this and a mess of other stuff from this era. It's all lumped together in new arrivals. All Texas poster artists and all this stuff is around 30 years old. I think I got the date of the poster next to all the venues. These guys are amazing.
Gilbert Shelton created the Fabulous Furry Freak Bros.
