I got the same set, plus a briefcase, for high school graduation in 1967, only it was a vibrant turquoise. I still have it, but yours is in much better shape than mine. I really need to just remove the lining and redo it entirely. The outside is still in great shape, with just a few minor scuffs. They really were well made luggage pieces.

I haven't used them for at least 10 years though, as my senior citizen body and joints much appreciates having good wheeled cases these days.
