Another piece of Senna memorabilia is up for auction

After the high-profile sale back in May of Ayrton Senna's Monaco-winning McLaren MP4/8-6, another piece of memorabilia associated with the legendary Brazilian is up for auction.

It's also a relatively affordable bona fide artifact - although still estimated at around £70,000 by RM Sotheby's - that will be on offer in London in early September.

According to the consignor, a former mechanic and racing driver and a friend of Senna, the kart was used by the Brazilian in the spring of 1994, on a track located on his farm in the town of Tatui, where he had invited friends for a day of karting and fun.

This was just six weeks before Senna's tragic death at Imola on May 1, 1994.

Ten percent of the proceeds of the sale will be donated to the Instituto Ayrton Senna, the non-profit organization founded by the Senna family that helps provide quality education to young Brazilians.

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
