Mitsouko Cologne by Guerlain Paris

I collect non-commercial vintage perfume bottles and vintage Guerlain bottles are highly collectible, especially if they are Bacarat and/or still have perfume and the original box. A quick search on eBay of completed listings for your perfume in the last 10 days show that an empty bottle-no box, sold for $15 and an unopened bottle w/the box still sealed sold for $360....and every price in between, depending on how much perfume was still in the bottle, if it has the original box, etc... A good reference book is Antique Trader: Perfume Bottle Price Guide. *--Modern commercial perfume bottles are collectible too!* Hope this helps!!!
