Rare vintage Bailey's 1970s embossed glass mug, never used!

this is a lovely find!! An original Bailey’s Irish Cream clear glass mug with logo. Mug is very heavy, thick glass with a large handle. Mug features the large double "B" logo embossed on the exterior as well as "Baileys" in a a curved rectangle on bottom. Mug measures 4 1/2" tall x 4 3/4" wide (including handle) x 3 1/2" in diameter. 12oz. Very difficult to find an unused version of this.
