NEW YORK, NY.- Heritage Auctions again is expanding its New York City offices at 445 Park Avenue (at 57th Street).

The addition of more office space on the building's 15th floor will free up street-level floor space to expand public displays of historic collectibles from Heritage's 39 different auction categories, including sports memorabilia, rare coins, comic books, entertainment and music memorabilia, books and manuscripts, wine, luxury handbags and fine and decorative art.

"We opened our Manhattan gallery and offices in September 2010 and increased our space by 25 percent just two years later. We've now signed a lease to expand our office space on the 15th floor by 50 percent. This brings the total square footage at our Park Avenue location to 10,232," said Heritage Auctions President Greg Rohan.

"To give you an idea of Heritage's dedication to the New York market and to this office, the per square foot rent on the new space is about 40 percent higher than on our existing space on the 15th floor," he explained.

"One of the most talked about features of our New York gallery is the Heritage Window on Park Avenue. Thousands of people pass by each day and enjoy eye-catching displays of selections from upcoming auctions," said Kathleen Guzman, Heritage's New York Managing Director.

"After we move some of our ground floor offices to the new space on the15th floor we'll significantly expand our lobby area exhibit space for collectors and the public to see even more displays of rare and historic collectibles and art," explained Guzman.

Dallas, Texas-based Heritage opened its New York City gallery and a Beverly Hills, California gallery and salesroom five years ago at a time when many major auction firms were contracting during the economic recession.

Heritage is the largest collectibles auctioneer and third largest auction house in the world, as well as the largest auction house founded in the U.S. The firm has more than 900,000 registered online bidder-members, and more than $900 million in annual revenues.

Heritage Auctions New York gallery, 445 Park Ave. (at 57th Street), is open Monday through Friday from 10:00 AM to 6:00 PM. The phone number is (212) 486-3500.
