Despite attending his first race as the 2011 champion-elect, it was Sebastian Vettel who doled out a present in Korea.
The Red Bull driver had learned that Rubens Barrichello, the Brazilian veteran, is collecting F1 drivers' helmets.
"Great surprise when I received a helmet that was missing in my collection. Thanks Vettel," the Williams driver wrote on Twitter.
German Vettel, 24, signed the helmet with "your friend".
Barrichello revealed that he has the helmets of "many" current drivers in his collection, including Mark Webber, Jenson Button and Jarno Trulli.
"Almost everyone on the grid really," added the 39-year-old.
SID news agency said the helmet gifted by Vettel was the one the German wore to second place behind Lewis Hamilton in China this year.
