I have heard that for The Macallan - Anniversary Malt - 1928 50 year old, it comes with a personal letter of authenticity from the then chairman of Macallan Allan G. Shiach.
May I ask if all bottles have the letter or only some of them?
Also does anyone have a picture of how it look like?
Currently I have a bottle of it, but I do not have the letter. Does this mean that it is fake? Or just the specific bottle does not come with it, or it is misplaced?
