Superb boxing broadside featuring a very young and undefeated Cassius Clay taking on veteran Archie Moore. Measuring 14x22" with black print on a bright orange background, the on-site poster heralds Moore as the World's Light Heavyweight Champion, and Clay as The Undefeated Louisville Lip, in what was his first pro Heavyweight bout. Note that the date listed is October 23 at the Los Angeles Coliseum, which was the originally scheduled date, though the fight took place as the LA Memorial Sports arena on November 15. Though multiple folds and some wear are present, the heavy paper stock remains in amazing condition with no foxing evident. Clay - shortly to change his name to Muhammad Ali - remained undefeated with a 4th round knockout, which he predicted in his pre-fight poem.
