A LEGO set of the Back to the Future DeLorean which was recently on display Comic-Con and will go on sale Aug. 1.
The set comes with LEGO mini-figure versions of Marty McFly and Doc Brown, while the time machine includes details like the Flux Capacitor, a time display tile, and the Mr. Fusion Home Energy Reactor.
