Thanks again guys. I left 20 posters with the band to sell at the gig last night. Bearing in mind the seeming difficulty of selling posters at gigs here in the UK, I assumed that half or so would sell. I just got a message from the band this morning and apparently they ALL sold out very quickly, which I'm really happy about. Definitely a good thing to happen here in the UK for making people more aware of poster art and the silkscreening process!
I appreciate the connection ("How I..." etc.) but I still think ripping off the whole illustration is a bit shoddy. A shame because some of your other stuff is really good - perhaps this was a rush job?
