Locker-Room Memorabilia is lucky enough to have a great relationship with exclusive client Justin Upton of the Arizona Diamondbacks.

These autographed Game Used Adidas Spikes were signed by Justin during a private signing. These spikes were Authenticated by Major League Baseball

As always, every hologram item we issue is obtained in person by a Locker Room Memorabilia employee. Because of this we are able to provide several photos of our athletes signing our products. Look for the copyrighted photo of each of our athletes signing the item. At Locker Room Memorabilia, we don't tell you the item is authentic, we prove it
