Joe Walser, team leader of Time Machine Restoration and co-organizer of
We're Going Back helped design the lifesize clock tower clock and the entire line of BTTF products for EFX. It also comes with the panthers.
Here is a image Joe recently shared on FB. Even if they are not selling the 1:1 scale version, the miniature replica is a great piece to have.
So far the replicas include:
Lifesize Clock Tower Clock with panthers
Clock Tower Clock Miniature Replica
Lyon Estates Book Ends
Pitbull Hoverboard
Biff's Cane (not seen in the photo)
