A friend just gave me a bottle for xmas

A friend gave me a bottle of Ezra Brooks real sippin whiskey collectors series.
Its 90 proof- 12 years aged and the bottle is genuine china. The bottom of the bottle says it was made in 1968 so aged 12 years im guessing this means its 1956. Its in the original box and the bottle has never been opened. Great shape and seems to be unique. its an old rail car bottle. says powell and hyde on a banner on the bottle. Any info would be cool. Awsome xmas present cant wait to hear some info.
