Solidifying the provenance of this lot, all articles were presented to Tyson in-person last year, who personally verified their provenance and signed and inscribed the trunks, the photos and also agreed to sign both LOAs! Confirmation direct from the Champ himself! A fine memento of the most terrifying fighter ever to step through the ring ropes. Letter of provenance from Steve Lott. Letter of provenance from Craig Hamilton. COAs for Tyson's autographs from PSA/DNA.
