Hey awesome!!!...that's a new one for me!...thanks for the link too, a friend of mine in Alberta would love to acquire this I think!happened to randomly come across a 7 up lady from Medicine Hat Alberta on etsy , there is one for sale , this bottle was mentioned but one has yet to be posted . this one is also from a different bottler " Superior Beverages " than the shield bottle in above picture .
I showed it to my friend and he has not seen it either, he does have one from Medicine had buts marked National Fruit Company ltd....So this Superior 7up is post 1947. I'm not sure which bottler had the franchise first as I've never researched either bottler, it's possible National bought out Superior.it can't be that common if neither of us have seen one before and we've both seen a lot of 7 up bottles I'd imagine
