Byamba entered the world of professional Japanese sumo with the rush of other Mongolian wrestlers in the early 2000s. One of the greatest rikishi of all time is the Mongolian Yokozuna Hakuho who has sat on the top of the sumo world for the better part of a decade now. Byamba (His shikona was Daishochi when he was in the Nihon Sumo Association) seemed destined for similar success, but was sidelined by an injury right before he broke into the top ranks and retired soon after. After he retired from professional sumo, he turned to amateur status and won two Sumo World Championships in the heavyweight class as well as Gold in the 2009 World Games. In 2013, Topps captured Byamba in their Allen and Ginter's "The World's Champions" set. From what I gather there at ~10 different types of cards of Byamba in this set:
Regular Red Back #/25
Mini Wood #1/1
Mini Auto Red Ink #/10
Black, Cyan, Magenta Printing Plates
Good stuff. I am hoping to slowly add more of these to my collection over the years.
