[QUOTE=AJIEKCEu;3421471]Help to identify the authors, and the cost of the work.
And if possible, a little bit about the paintings and pictures, the years of writing, what they are and what they napisany@

1-I work, perhaps watercolor or watercolor-gouache drawing. Good. But to salon (commercial) level seems to be slightly below. Although the school is good. May work poorly stored. But interesting to see other works by this artist.
2-I work. Graphics. You can print, applique. The average work.
3-I work - pictorial sketch. The author is a painter. Interesting to see his commercial work
4th job - entry level training.

Salon schedule 70-ies was worth approximately 50-500 bucks in today's money and without name.
