Marking its 10-year anniversary as a leading auction house in the nation’s capital, The Potomack Company recently announced the appointment of specialist Kathryn Coldiron to head the company’s newly expanded Books, Manuscripts and Memorabilia Department.

We are delighted that Kathryn will be leading our efforts to identify important books, historical documents and political memorabilia for our clients,” said Potomack Company founder and owner Elizabeth Haynie Wainstein.

“With our location in such a historic setting so close to the center of American political life, Potomack’s past sales of political and historical items have been a natural fit for us and we are pleased that Kathryn will help us expand in this area.”

Ms. Coldiron was previously Director of Books and Manuscripts at Leslie Hindman Auctioneers in Chicago, and holds master’s degrees in medieval history and library and information science. Her expertise extends to cartography and natural history prints as well as early printed books and bindings.

“I love original bindings and the smell and feel of old books and paper,” said Ms. Coldiron, “and I look forward to exploring some of the interesting private libraries in the Washington area.”
