These were autographed by Lea Thompson (Actress from back to the future 2) at a Comic Con, picture proof provided. This bundle comes with the autographed shoes, autographed picture, and the 3 memorabilia license plates. These were only worn one time, which was during the comic con that they were signed at. The lights turn on when plugged in, I cannot confirm whether they hold a charge anymore as these are from the original release. Great collectors piece for back to the future fans. I am also quite certain this is the only pair signed by her, as she stated that she had not seen a pair since the filming of the movie when signing.
