Well, this is a find. Chris points me to these set photos from Charlie's elusive How and Why pilot, via the website of Molly Hughes. Hughes was the production designer on How and Why and I'm Thinking of Ending Things.
Loads more at the link! Oh, you guys. Aaahhh, now I want to see this damned show even more. Silly Hollywood. (And if you're about to ask: no, I have no idea where or when we can see this pilot, but we probably never will. Tons of pilots get canned and never see the light of day.) You can also check out a handful of Ending Things photos on Hughes' website.
Thanks Chris!
