A boy with a lemon
 

Help please install the artistic value and perhaps the author.
Oil on cardboard, 70x50 cm, probably the end date of 40th-early 50s.

Can, 60-70s?

I would have dated it early and mid-1960s, a typical "severe style", close, perhaps, to Gavrilova.

But more - far from Gavrilov.

But the spirit of the age is definitely a picture.
