This year's Hershey auction by RM Auctions promises to the most exciting yet, according to the firm.
The sale will be held in Pennsylvania, US, from October 6-7 with highlights including the 1884 De Dion Bouton et Trepardoux steam car (shown in the above video).
Driving "La Marquise," Bouton participated in the first motor car race in 1887 (he was the only car to show up) averaging 16 mph for the 20 miles from Paris to Versailles and back.
The motor hit 37 mph on the straights, according to an observer who timed him. The next year, De Dion in "La Marquise" beat Bouton on a three-wheeler, at an average of 18 mph.
De Dion's car will be estimated at $2,000,000-$2,500,000.
Also among the many brass era cars and horseless carriages will be several electric cars, the likes of which rarely ever come to market.
Among them, the 1913 Argo Electric Fore-Drive Limousine. Formerly in the James Cousens Cedar Crossing Collection, and prior to that in the John McMullen Collection, this car is believed to be the sole surviving example of the marque.
The car is expected to bring $100,000-$150,000.
The same holds true for the 1907 Baker Model M Roadster, the Swiss-built 1905 Tribelhorn Electric Brougham and the 1903 Columbia Electric Surrey, which are also featured in the same auction.
Of particular interest is the 1920 Detroit Electric Brougham.
One of very few survivors, it was delivered new to Ms. Margaret Gray of Chatham, Ontario, home to RM Auctions headquarters.
A late electric car with faux radiator, it has been restored and is exceptionally well documented.
