This jersey is a Bulls Nike NBA jersey size 50 signed by NBA's GOAT, Michael Jordan, in silver Sharpie. Great signature overall which stands out on the black of Jordan's number 2. Jordan's autographed stuff is continually trending up in value, this is a great long-term investment of arguably the greatest of all-time. The jersey is authenticated by Upper Deck - Cert # BAF36093 which is attached on the jersey and comes with COA from Upper Deck directly. Great addition to any Jordan collection.
