"What Is It???" Wednesday: Message in a Bottle

I had a surprise visitor drop by the center yesterday who gave me the best excuse to get out of my desk and explore one of the new exhibits in town.  I'm in love!  Exhibit to be featured tomorrow on the blog, but thought it would be fun to put out this WIIW teaser.

WHAT IS IT???

Obviously a bottle, but what's your best guess on the date.  AND bonus points if you know where it was found.

Correct guess on bottle gets you an "I Dig 1565" bumper sticker (or new St. Johns County bumper sticker if you already have 1565).  First to guess location of the find gets a t-shirt!
