Since 1985, we have successfully served an extensive client base, including museums, libraries, universities, and private collectors. We have paid many millions of dollars for documents, ranging from one piece to major collections involving thousands of items. For decades our frequently issued auction and fixed price catalogs were widely anticipated and viewed by thousands of collectors worldwide..Today, we rarely issue sales catalogs and our business is generally conducted through the internet and private sales. All items we sell are Unconditionally Guaranteed to be Authentic.
