Auction house eyes millions for Banksy's Silent Majority

Painted by one of the world's most famous street artists, installed first at a mud-soaked music festival and then beneath an oak tree, the trailer was home first to an itinerant British couple and then their growing family.

In 1998, the truck owner knew Banksy as someone he had once busked with in Bristol, the United Kingdom, and the friend of his sister's boyfriend, and for 200 pounds (about $300 at the time), he agreed to turn his trailer into a blank canvas for the Glastonbury music festival.

Recently pried off the trailer, the work called Silent Majority, which depicts a commando raid to install sound gear for a rave, went up for auction on Monday in Paris.
