Summit Sotheby’s International Realty; the blue sign, classic branding and a worldwide network backed by the 273 year heritage of the Sotheby’s Auction House. Twice monthly I will feature on my blog articles of interest from the Auction House. Kicking off the collector car auction season on a strong note, RM Sotheby’s returns to the vibrant grounds of the Arizona Biltmore Resort & Spa in Phoenix, 17–18 January, for its 20TH ANNUAL ARIZONA SALE. Set to continue the company’s strong track record in Phoenix, presenting more than 100 blue-chip automobiles from the world’s most iconic marques. Hand-selected by RM Sotheby’s international team of specialists, the catalogue will span the spectrum of the market, from pre-war classics and contemporary supercars through important sports and racing cars.
