I stumbled onto a website focused on writing about cars, and found they'd made a couple articles on art cars, and looking through to see about "new to me" examples, found that "driventowrite.com" had found my article on Delaunay!

that delights me, as I think I may have the most comprehensive coverage of Delaunay's art online. https://justacarguy.blogspot.com/search?q=Delaunay
