Larry Mahan · Identification

Construction / ID tells

Labels reading Larry Mahan, Larry Mahan by Hyer, or later factory marks. Era depends on maker: Ben Miller, New Hyer, Tony Lama, or later licensees.
Not a custom shop biography. Current third-party “custom shop” pages are not the historic line.
Person ≠ pair. A rodeo-champion portrait does not authenticate an unlabeled boot.

Maker-specific markings guidance has not been documented yet. Preserve the complete stamp and compare it against dated sources.
