1970s vintage Kool Aid drink mix packets lot, unopened packages

Lot of vintage Kool Aid fruit drink packages, carefully kept for about 40 years in a old peanut butter jar (glass with metal lid, same approximate age as the Kool Aid, I think!) This is not a collectible we often see, and I don't think we've ever found Kool Aid any older... this is around Funny Face vintage, 1970s.
