I've just noticed that I did these 3 doodles (which I've shown before) exactly 41 years ago today (yesterday). October 28th 1974.
Funnily, I was recently in the small nearby town where they were drawn, and the trees are looking exactly the same, just a tad older.
Plane trees are a big element in the French urban landscape; they dominate many a town square and avenue. France wouldn't be France without them.
