Vladimir, I think so too, thank you. And the third girl from "Sovkomovskoy" pictures too, have a "Razdole" - written by a little differently, but in my opinion, it is!
I am now more puzzled "The boys ran out of water" (can credit "Sovkom" at the very end of my previous post). Provenance is the same - a private collection, but the puzzling presence of expertise GRM (though we have not seen her) ... I think these "boys" - close relatives of those "running girls". Or is it still a preparatory board (what little hard to believe)? But where the engine got to

? Gentlemen, share your views!
