Interesting story, but God, how I hate that style of illustration and art. Not sure how I feel about the artist saying he doesn't want the pieces sold. I wonder if the bar asked him to do it, or if he did it on his own and they were cool with it. If it's the latter, I get that it's his art and he created it, but it seems a little tacky to withhold a potential payday for the bar because he wouldn't (I assume?) get the money. Maybe it's no different than a musician being asked to play for free because people don't get that music is work.
Maybe it's also that I think his art sucks so I doubt the value and don't want to see it do well. Who knows!
