Stumbled upon the web site of artist Eric Dowdle, and it turns out he makes folk art pictures in a style which is very similar to that of many old amiga games. It's so similar that it's almost scary, and I can't find any connection to the game industry.
Just look at this picture: https://www.dowdlefolkart.com/fine-art/detail/yosemite/
Could have been a screen from Chuck rock if it wasn't for the cars!
What do you think?
