Double Decker Bus Christmas ornament from Merck Family's Old World Christmas. **New for 2008** Made of mouth blown glass and hand painted by master craftsmen.
Red Double-Deckers have been London's trademark for almost a century. They are taller than other buses. A police order forbidding trailers behind trams, which were thought to be dangerous, inspired companies to "put the trailer on the roof", and the double-decker bus was born.
