One of the rites of summer in America's finest city, San Diego, California, is attending the largest convention of its kind, Comicon International.
Aside from being one of the most amazing people watching places on earth, Comicon also has some incredible collectables and memorabilia, the likes you have never seen.
Like the Hot Wheels 'Twin-Mill
What's amazing about this giant toy is that everything works on it: headlights, taillights, sequential turn signals, and two complete sets of gauges. It starts, it stops, it turns. And when those twin 502 big-blocks roar to life with an estimated 1,400 total horsepower, the car gets everyone's attention.
Enjoy the photos of the twin-mill and some of the sights and scenes of Comicon International.
And yes, that IS Yvonne Craig, the original BatGirl in the gallery of photos below.
