Darth Vader Hot Air Balloon.
The Darth Vader Balloon is an 86 foot tall hot air balloon replica of Darth Vader’s helmet.
Belgian balloonists Benoit and Michel Lambert commissioned specialty manufacturer Cameron Balloonsto build the Darth Vader Balloon in 2007 (of course, only after receiving the official Lucasfilm OK).
The Lamberts now pilot the balloon in appearances all over the world. It will be featured at the Great Reno Balloon Race, September 9-11, 2011.
