Bit mundane I know, but Marussia tied up a number of deals prior to the Australian GP with partners, sponsors and suppliers, some new, some renewed.
Advanced lighting company JCC:

http://www.marussiaf1team.com/news/552/The most important of these is the renewed deal with CNBC because of their exposure on the cars, it's clearly a fairly substantial deal, though it's good to see the team getting out there and signing up new deals all the time. They clearly have a good marketing department!
Not sure (with the exception of CNBC) how many of these deals will see new logos on the cars, but either way it's all positive news!
EDIT: There's also a pretty cool video on the team's website showing some of the footage from Silverstone when they shook the car down and some soundbites from the drivers and Lowdon and Booth -
