Question: Kentucky Tavern Derby Winner; series history?

[westcoastinvader]

Just a quick personal question.

Anyone know when the Kentucky Tavern Kentucky Derby mirror series began?

I've found as early as the mid-1980's, but haven't seen any earlier with cursory efforts.

Apparently Kentucky Tavern is now owned by Constellation Brands, and their corporate website offers a cold "check your library" type response on any historical questions of brands they have acquired. I've looked a bit further on the internet with no luck to date.

I love the series, and have a couple hanging in my sports viewing/computer/library/movie "TGI Fridays" room. Just wondering if it's worth any effort to go looking for mirrors earlier than the mid-1980's.

Thanks in advance.
