Welcome to Richard Polsky Art Authentication. We specialize in authenticating the work of four legendary Contemporary artists: Andy Warhol, Jean-Michel Basquiat, Keith Haring, and Roy Lichtenstein. We also authenticate the work of Jackson Pollock, a Post-War artist who achieved mythic status. We believe that authentication is the bedrock of any art market transaction. Our approach to evaluating works of art is based on transparency, expertise, and fairness. Whether your property is found to be genuine or not, the written report you receive will clearly explain how we came to our decision, providing you with a substantive document.
