Vintage Collector’s Thierry Mugler empty flask

This is a vintage item for collectors. This Thierry Mugler Angel Men is an empty metal travel size flask. It has a mark on the back as shown in photo. Included was a special CD promo and is accompanied with a copy of the letter (11/27/2008) with the name blocked out. It was a gift to my father. The CD was never played, but found the letter saying to scratch it to release the scent. For privacy reasons, I blocked my father’s name.
