Top of the line 1989 Michael Jordan Chicago Bulls signed game worn jersey. Displays nice wear with "89" year tag, "2' LB" tags on front tail, along with Chicago Bulls tag and Sand-Knit size 44 tags on tail and all letters and numbers pressed on. Signed on front with a beautiful period signature in black marker. Purchased from a charity auction on May 5, 1990, this lot also includes a neon yellow-green runners cap from the charity event held at The Multiplex, at which the Bulls trained in the late 1980s. Per the included Letter of Provenance, our consignor bumped into MJ numerous times and explains how he acquired this classic jersey during the auction. Chicago caught fire throughout the 1990s, winning six NBA titles in a span of eight years, with Jordan taking Playoff MVP honors in each of those six championship seasons. MEARS A10 LOA.
