If you want more information on your 1947 bottle of Chivas, please send a clear photograph to Chivas' PR & Heritage Co-ordinator - The email address is
HERE.
Chivas told us they do not offer valuations, but suggested you contact the company McTears Auctioneers. Try contacting Martin - his email is
HERE. You can bet he'll want some pretty sharp photos of your Scotch - especially of the label and seal.
Good luck!
