Patricia Jobe Pierce and Marco Apollo Pierce authenticate artwork for collectors, dealers and leading auction houses. We are world authorities on Edmund C. Tarbell, John Joseph Enneking, William S. Barrett and Chauncey Ryder. Please see raisonnés for catalogue information.
We charge no fee to authenticate an artworks by Tarbell, Enneking, Barrett, or Ryder, as this would be a conflict of interest.
