Story highlights Senna photograph up for auction

F1 great died 25 years ago

Image estimated to sell for $3,000

(CNN) An iconic portrait photo of Ayrton Senna is expected to sell for nearly $3,000 at a London auction, 25 years after the racing driver's death.

The pensive shot of the Brazilian F1 great was captured by sports photographer Chris Smith during a practice session of the British Grand Prix in 1991.

It is one of a number of Smith's photos up for sale at Chiswick Auctions on May 16, with Smith's snap of Muhammad Ali and the Beatles expected to attract a bid of more than $6,000.

Senna, who died the day after crashing at the 1994 San Marino Grand Prix, finished fourth that day at Silverstone on his way to a third and what would be final championship title.

Considered by many the greatest racing driver of all time, Senna's death has been deeply mourned by millions of adoring fans, notably in his native Brazil.
