Works by an obscure Armenian-American abstract impressionist discovered in a Long Island cottage have been appraised at $30 million.

In 2007, the new owner of a Bellport bungalow found thousands of paintings, drawings and journals by Arthur Pinajian in a garage and attic. News 12 Long Island says Peter Hastings Falk valued the works. He once appraised art from the Andy Warhol estate.

Some pieces already have sold for $500,000. Fifty of the landscapes are currently on exhibit at Manhattan’s Fuller Building.
