THIS IS MOST DEFINITELY AN OLDER COBALT GLASS BOTTLE, YOU CAN SEE THE IMPERFECTION IN THE BOTTOM AS IT LOOKS SLANTED INSTEAD OF PERFECTLY FLAT ALL THE WAY ACROSS. YOU CAN ALSO SEE ALL THE BUBBLES INSIDE THE GLASS. IT APPEARS TO BE A LITTLE GRADIENT IN COLOR, GOING FROM LIGHTER TO DARKER AT BOTTOM. PLEASE LOOK CLOSELY AT ALL PICTURES AND DECIDE FOR YOURSELF IT'S AGE. I'D SAY PRETTY OLD! MEASURES APPROXIMATELY 11-1/4" TALL WITHOUT CORK AND APPROXIMATELY 3" ACROSS BOTTOM. COMES FROM SMOKE/PET-FREE STORAGE.
