I had to research this as I've suffered some severe memory loss recently! The Group Avatar is "Composition à la main et aux chapeaux, 1927" by Fernand Léger.

I'm about two hours early for posting in this group this evening, but it feels like a somewhat unreal day today. Not only is it a Bank Holiday but I only had one thing scheduled and that seems to have been passively cancelled on me. Still, a good chance to catch up with films stored on PVR which were beginning to grow out of hand.
