RARE VINTAGE YSL Cashmere silk wool? Gorgeous plaid scarf w/fringe edge detail

Incredible rare find of a Yves St Laurent YSL wool and cashmere and silk blend scarf. There is no content tag so that’s what I suspect it is. Content is unknown, but I suspect it is a blend of wool, silk and cashmere. Fringed edge on all four sides measuring approximately 30“ x 33“ in a square shape beautiful plaid black watch style print with classic YSL signature on one corner. Good vintage preowned condition. One of a kind and super rare! I suspect this was from the 70s!
