A plan has been launched to resurrect the Olympic Stadium wrap, a 900m (984-yard) hi-tech fabric curtain surrounding the showpiece venue.
London 2012 chief executive Paul Deighton has opened up the bidding for a private sponsor to supply the wrap, which was controversially scrapped to save £7 million after the Government's spending review in October.
Companies who lodge expressions of interest by the February 18 deadline will be in line for sector exclusive marketing rights as part of the procurement.
International Olympic Committee (IOC) guidelines do not allow branding in venues, so the wrap will not display sponsor logos during the Games, but the offer to reinstate the wrap is also a high-profile deal.
More than four billion people worldwide are set to see the 80,000-seat venue when they tune in for the opening and closing ceremonies plus the athletics competitions.
Mr Deighton said: "We have had significant interest in supplying the stadium wrap from the private sector so now is the time to start a formal tender process.
"There are some exciting ideas around and we are running a process that is fair to those organisations that have expressed an interest."
London 2012 has raised £670 million of a £700 million domestic sponsorship target. It must raise £2 billion from the private sector to stage the Games.
It is billing the wrap deal as one of the last high-profile opportunities for a corporate sponsor to link-up with the £9.3 billion Olympic project.
