“Things go better with Coke.”
This particular style of Coca Cola ad campaign ran for two years from Dec 1963 to Dec 1965 (as best I can tell). Like the ads from earlier in 1963, these continued the trend of plain white background studio shots into early 1965.
Apart from a couple at the end of the year, the white studio backgrounds faded out by mid 1965, making way for outdoor shots.
There was also a selection of ads with food or just the bottle/glass.
