July is often admittedly a quiet time for auction houses, but every month may have its moments of trend defiance and this one was no exception. While the headline 19th and 20th century names that command eight figure estimates in New York, Paris, and London await Marquee Week and other blue-chip sales events, the sales that generated excitement had character of their own. Sotheby’s Geek Week is always a highlight of the New York City summer. Across the Atlantic, the Old Masters were attention-worthy. And Hollywood itself had something to offer from one of the most beloved films of all time, The Wizard of Oz. Here are some of the auctions that stood out in July.

“Gus,” the Tyrannosaurus Rex | Sotheby’s New York

One of the most complete skeletons of a T. Rex ever assembled, the set of bones affectionately known as “Gus” broke the record for dinosaur bones when it sold for over $50 million in the “Natural History including Gus Rex” sale. The previous dinosaur record of $44.6 million was held by a stegosaurus called “Apex,” now on a long-term loan to the American Museum of Natural History.

George Washington’s Letter Transmitting the Constitution to Thomas Jefferson | Christie’s, New York

Jefferson was serving as the U.S. Ambassador to France when he received this letter from Washington. The letter is dated September 18, 1787, but did not reach Jefferson until New Year’s Day of 1788 after Captain John Paul Jones, the man charged with delivering it, delayed his departure for Europe until November 11. By that time, Jefferson had already learned about the Constitution from other sources. While the original receipt of the missive was subject to 18th century delivery hazards, its recent sale was well-timed for the country’s 250th anniversary, achieving a price of $2,759,000 against an estimate of $1,000,000–2,500,000.

Over 500 years old, it is in an excellent state of preservation and captures a tender and universal moment between Mary and her son.
