This is a vintage 3rd quarter 20th century decorator painting done of a landscape with cottage that is done with brush and palette knife that is signed Tirolf. There is some speculation that the artist may be a Hein Tirolf from Holland, however this could also be a fictional name and the work is more likely a product from China or Mexico. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
