A local illustrator, caricaturist and courtroom artist Dana Verkouteren just shared this painting with me, noting it "was one Richard painted after he, Bono [Mitchell], and Linda Lunsford were up at Deep Creek lake with me, for a late autumn weekend. It was an incredible thank you gift that I treasure! Honestly, even looking at it up close, I’ve no idea how he created that image.
Thanks to Mike Jenkins for the tip.
