Coke started in Georgia, is huge across the south. Has marketed itself as like a family friendly or wholesome nostalgia brand for a long time. Which plays really well with the old white people.

So we’ll in fact, there are swap meets and clubs for collecting Coke memorabilia. https://www.cocacolaclub.org/content.aspx?page_id=22&club_id=534374&module_id=394442

I’ve run across these meets/conventions while traveling for work. All the attendees are boomers.
