As Michael Schumacher heads for Spa this weekend, odds-on to clinch his seventh World Championship, a unique hand-made wooden replica of a Ferrari grand prix car is up for auction on eBay, signed by 25 current and past F1 drivers. The auction started at just 1 euro and is at .

In 2000, Michel 'Mikey' Keysers, a skilled cabinet maker who lives near Spa Francorchamps in Belgium, spent over 1,000 hours crafting the full-size replica Ferrari from several different woods. The following year, during a special exhibition at Spa, the model was signed by world champion grand prix drivers Michael Schumacher, Mika Hakkinen, Jacques Villeneuve, Alain Prost, Nigel Mansell and Niki Lauda.

Other F1 stars who have also signed the car are: Rubens Barrichello, Ralf Schumacher, Kimi Raikkonen, David Coulthard, Jarno Trulli, Jenson Button, Olivier Panis, Jean Alesi, Gerhard Berger, Giancarlo Fisichella, Heinz-Harald Frenzen, Eddie Irvine, Nick Heidfeld, Jos Verstappen, Ricardo Zonta, Mark Blundell, Martin Brundle and Eddie Jordan.

The beautifully finished Ferrari, lacquered and painted using the same process as a real grand prix car, is 4.7m in length and weighs around 500kg, but it can be dismantled for easier transportation. This international auction is timed to end next Monday (August 30), the day after the Grand Prix.
