WTB: Washington, DC /Baltimore, MD Stamp Collections

As a stamp dealer living in Rockville, MD, I am available to purchase of
appraise stamp collections in the Washington, DC and Baltimore, MD areas. I'm
interested in U.S. and Worldwide Collections, covers, FDCs- anything
philatelic. I'm a long-standing member of both the American Philatelic Society
and the American First Day Cover Society. If you wish to contact me, please
e-mail : . I advise against responding on this board, as I
rarely view it.
