A friend showed me a copy of the Loudoun Now newspaper today, and it had work by an editorial cartoonist I didn't recognize. A little bit of digging revealed it was done by Stilson Greene and ran in his weekly Stilson's Corner in the paper, which is archived back to March 2016. I've reached out to try to get our standard interview questions answered.
A lot of small papers may still have editorial cartoonists that aren't listed in the big run-downs of the death of editorial cartooning. The Daily Cartoonist linked to a story about Peter Waldner today for a second example.
