You have a vintage mid 20th century framed color printed reproduction of a painting by Pierre Auguste Renoir (1841-1919) of his 1883 portrait painting entitled By the Seashore. The one and only original of this painting is in the collection of the Metropolitan Museum of Art in New York City. If you look closely you will see a dot matrix pattern on the surface that is indicative of machine printing. It was common throughout the 20th century for publishers to print images of paintings and sell them as decorative wall art through decorator, furniture and framing shops. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
