Thank you for submitting your item for appraisal. This appears to be a painting by an unknown amateur artist of the second half of the 20th century, signed JAN. The artist manages to convey the feeling of a lush meadow beneath a blue sky. No artist with that name working in this style is listed. It is a painting for home decor and as such has a value one would pay for decorative wall art.
The estimate is based on similar offered or sold at auction.
