Rare 1960s Black leather motorcycle jacket

Purchased at famous vintage store, Flashy Trash in Chicago in the early 90s. Rare and from the 1960s!! Estimated to be a men's size large. The only label/tag on it is pictured (“professional leather clean only”. Zippers and snaps all work. Has been hanging in a closet for decades, but was well loved and used in the early 90s! Inside lining is torn at cuffs.
