Early times bottle unopened with tax stamp and box. Date uncertain... Any help would be appreciated

This item came out of a drugstore / soda jerk fountain in older Louisville. The Yellowstone bottle in the background is from 1970 (6 yr). I picked up the Earlytimes Christmas bottle due to the fact that the box was intact and the bottle itself is unopened with the original tax stamp across the top. I was told the bottle his from 1960 but I am uncertain because I have never seen another bottle like this to compare to.
