This bottle states "Ohio Bottle Swap 5-19-79", as it is embossed on the face.  On both sides of the neck, it states, "No Return, Dispose of Properly".

     This is a glass bottle, about 7 oz.  It was given out to the attendees of the Ohio Bottle Swap, 45 years ago.  The top is a reproduction of the early blob top bottles from the turn of the 20th century.

     This bottle is perfect, with no chips or cracks.  

     Shipping for this rare bottle will be only $7.00, anywhere in the U.S.
     If you like, and choose to purchase more of my many asst. bottles, I will ship up to 6 FREE with this one.
