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

The cottage's new owner in 2007 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.

A recently published book by art historian William Innes Homer calls Pinajian's abstractions among the best of his era.
