Barrichello's 300th GP T shirt

Rubens Barrichello will reach the amazing milestone of 300 Grand Prix starts at Spa in two weeks from now.

And to celebrate he has produced a commemorative T shirt, which he and his sons Eduardo and Fernando have been modeling in the last 24 hours on Twitter.

No doubt there will be a fair bit of public demand for these shirts. He has not yet indicated how many he's producing and whether they'll be for sale, but Rubens tweeted that there will be some kind of draw. If you want one, best thing to do is to sign up to follow @rubarrichello on Twitter and await further details.

I remember Rubens' debut season in 1993 with Jordan very well. He was on for a podium in Donington, but then retired just before the end with a fuel pressure problem.

Although he is one of the oldest drivers in the field, he still has a youthfulness about him and a raw enthusiasm for racing F1 cars which belies his years. And as he showed in Hungary, when he passed Michael Schumacher through a small gap next to the pit wall, he's still got plenty of fire in his belly.

Williams love him to bits and I understand that they are well advanced with renewing his contract for 2011. So the incredible total of Grand Prix starts will keep on growing.
