Introducing the VINTAGE LEATHER 2027 Bob Mizer Calendar! 28 pages of crisp, sexy, black and white photography featuring leathermen from the 50s, 60s and 70s! Printed on thick gloss paper, it’s a unique time capsule of bikers and leathermen — each model being part of Bob’s Athletic Model Guild. Many of these same models and portraits were included in his vintage Physique Pictorial magazines.
