Post office muralist, Karl Anderson was very impressiony (that sounds much sketchier than “impressionistic”) — or at least many of his paintings were. Changing light, small brush strokes, and a sort of fluidity are common in his work.
According to Google, Karl Anderson has made his living as a CPA since 1979. As Google also says that he died in 1956, this is quite an astonishing feat. Mr. Anderson may be our first supernatural post office muralist.
Before his second (or maybe third or fourth or…) incarnation, Mr. Anderson also painted several covers for the Saturday Evening Post.
