I have no information about the subject of this painting

which I love as a genre for the sort of dreamy future aspiration they represent

There is some vertical rippling to the paper toward the right side of the image

female and male too

Evocative Abstract / Architectural Vintage Snapshot dutch mending I have no information aboutI think the subject here is the corner of the interior of a building, but it is the abstractness and ambiguity that make it interesting to me, all about form and shade and composition. (I'm really not entirely sure which end is up!) Both crisp and soft feeling, better in hand, glossy surface. 4 3 4" x 4", very good condition. C. 1960s 70s I would guess.
