My cousin is an artist and said that Thomas Kinkade inspired her to paint WalMarts. Here is one such inspired painting: 
Not finding any more "Walmart" ones. Here's a Bed Bath and Beyond: And her very controversial (at the time of release) Nascar Jesus: But my favorite is "McPressionism" They're from a series she calls "Brandscapes" She's now a "moreganic" farmer. Her farm is called Garden Fort -Little plug for her current endeavor. -She's easily one of my favorite humans.
I think she may have sold them already. This was probably 5 years ago that she did them. She's also one hell of a violinist, but she's put all that aside and is fully dedicated to farming. Her and her soon to be husband bought an old farm house and have re established its old farm. They're pretty bad ass. -See link (edit) in previous comment.
