Grant is from Vancouver BC. Him and I started a band together when I was a kid. He did many posters back then. He now lives off royalities from sponge bod square pants. Has a radio show on SFU station CJSF http://www.cjsf.bc.ca/pguide/index.php?intday_id=5
The Cynics came up with a stock tour poster where you just add the info.
I have 20 posters that Greg Hip sent me that the artist did back in 1990 or so, there all great. I will try to dig them up and scan them, I think there at my mom's. I think the guy goes buy "expo 3000"
