Vintage Designer Men's Christian Dior 100% Silk Tie

Freshly dry cleaned vintage silk tie. Good gently used condition. Made in USA. A mark noted to the back of the tie as shown in the last picture. This was not present before I dry cleaned so I think something happened with the cleaning/drying process. It’s not a stain (it’s a water mark it appears) and I’d imagine would come out when cleaned again. The color is a light plum (purplish).
