From my collection of Mt Dew bottles, it seems that 1973 was the transition year for the classic "ya-hooo!" phrase. I say this because I have some 1973's with and without the phrase as part of the ACL label. That being said (and please correct me if I'm wrong), I'm wondering about the bottle paper/cardboard cartons/carriers, whatever the proper terminology. Like the early 1970's bottles, the Ya-hooo! phrase was also featured on the top handle of the cartons. But what I'd like help with is information as to how far into the 70's they persisted? For instance, might you find a 1975 bottle that does not have the Ya-hooo! ACL label, but was packaged into a carton with the Ya-hooo! phrase? Please, any insight into this issue would be much appreciated. Cheers
