The Harley-Davidson Museum in Milwaukee, WI, will be showcasing Captain America's bike today! Included in the display is a Captain America leather "rescue jacket," his signature 'A' helmet, and a shield he carries in the film. If you're in the Milwaukee area, make sure you check this out.
Update: I spoke with an employee at the museum and they said the display would most likely be up til the end of summer.
Captain America: The First Avenger stars Chris Evans, Hugo Weaving, Tommy Lee Jones, Stanley Tucci, Haley Atwell, Sebastian Stan, Dominic Cooper, Toby Jones and Neal McDonough. The film is directed by Joe Johnston and is scheduled for 2D and 3D theatrical release on July 22nd, 2011.
