I have been a Vendor at the Ventura Show and created three of the Posters for the show. Vendors regardless of what the show is about will respond by coming back if supported through purchases. If the crowd does not respond then the vendor most likely will not return.
My artwork there ran hot and cold depending on the featured Porsche model. The best year I had there was the early 9's. Now that group knows automotive art and are rabid about their cars.
I hope someone picks this event up. I'd like to do more poster work and keep sharing my Porsche art with the faithful. Anyone???
