Surf historians. Jericho Poppler question???

Hello. I’m a bit in a bind finishing up a project tonight and was wondering if anyone knew the time frame that Jericho Poppler was sponsored by Coca Cola. Was it in the '70’s or very early '80s? Thanks a lot for the help.

I searched Google and there is a link to something like “environmentalist” in a PDF file that you might check out: it’s about Jericho’s life. It’s said somewhere that she was “in her late 20s” when she was sponsored by Coca Cola. And she was born in 1951.

Thanks balsa. I think I might have seen that PDF but it never crossed my mind to just “do the math.” Stoked.
