Help determine the authorship of paintings
 

Good day!
Dear connoisseurs of art, please help identify the authorship and even the approximate price for the painting. The picture went to a friend by inheritance from his great-grandmother. Tentatively, he said, age 18-19.
Show you whether it makes sense, examine the painting with a view to its further sale?
