There aren't many Khybers in the world, let alone in our hobby. Both of these pieces were autographed to Khyber Oser—longtime auction copywriter, son of hobby stalwart Ron Oser, and co-author of the influential 2005 guidebook A Portrait of Baseball Photography (with Henry Yee and Marshall Fogel) that sparked a revolution in photo collecting. Philly-born Khyber was barely a teenager when he crossed paths with his then-heroes Mickey Mantle and Reggie White. The pair of items (an 8-1/2" x 11" auction catalog and 5x7 team-issued photo) haven't seen the light of day since the early 1990s. EX/EX-MT condition with black-Sharpie "10" signatures. Auction LOA from JSA.
