Jordan’s game-used official white MacGregor Sand-Knit Chicago Bulls home warm-up shirt from the 1989–90 season, featuring “Jordan” in red across the back with his famous number “23” in red and black below. The shirt is lettered “Bulls” across the front, and their logo appears on both sleeves. Five tags are sewn inside just below the collar: the MacGregor manufacturer’s tag indicating a size of 46; an exclusivity label reading “Designed & Tailored Exclusively for Chicago Bulls”; a tag denoting the year, “89”; a fourth recording the custom alterations, “3 LB”; and a blank white strip tag. In fine condition, with light wear throughout. Accompanied by a typed letter from the original owner, noting that he acquired it at a ‘FestaBulls’ dinner auction held to benefit the organization’s charity, CharitaBulls. He also writes, in part: “These shirts were sometimes worn before the game and also during the game on the bench and sidelines, depending on the player’s preference.” The 1989–90 season saw Jordan lead the league in scoring for the fourth consecutive year with an average of 33.6 points per game. It was not until the next season that he led the Bulls to their first championship, going on to win a total of six throughout the rest of the 1990s. RR Auction COA.
