Their Underground Supporter posters can be downloaded here and are designed to avoid infringing the guidelines published by Olympic organisers LOCOG.
"Working in the field of licensing and merchandising, the draconian way LOCOG has enforced the brand rules around small and medium enterprises wanting to show their support of the games has incensed us," says Rizon's managing director Dave Collins. "Total control for sponsors is not the Olympic spirit and certainly not in the spirit of British fair play."
He thinks LOCOG cold have generated revenue by creating a discrete official program called the 'official supporters program'. For a small fee businesses would be able to download a pack of approved marketing materials allowing them to demonstrate their support for the games.
