The CDavis Gallery has some work by Mark Brown for sale. One original painting entitled “The Escapist” and around 7 prints, all of which run about $20.
I haven’t seen this artist before, but one look at the work and you can see a little of a Joe Sorren influence. They are all great pieces, “Eddie the Yeti” and “Transplant” (above) being my favorite.
I can’t seem to find his homepage at all (if he has one) but I did see that he has an Etsy account, so you can snag some work from him there as well.
