YSL Muse Bag Vintage SL Muse Bag Vintage Black The Muse features a leather body, flat leather handles, gold-tone hardware, a top zip closure, an interior zip pocket, key lock and dust bag. Serial Number: 156464-467891. Measures approximately: 16" wide 12" height 5" deep 9" strap Really special bag as I believe this was the last bag designed by YSL before his death. Condition is very good with signs of wear on top near zipper (please see pics), but a shoemaker could make this bag appear brand new. Corners and bottom of bag still very clean. Incredible quality bag with tons of use left. Chic and classic forever staple.
