Although the Nehi brand dates back to the '20s, that one dates to around the '60s. May be a date code on the bottom to pin it down a little closer, but I can't tell from the pics. Might want to post them in "Sodas - Embossed, Paper Label & ACL" for better input.
I drank Nehi grape, peach, and orange soda all the time in my youth in the 60’s. The company is still around and is called the Royal Crown Cola which was also a popular drink in the mid 1900’s. It is also still made. Both are sweetened with cane sugar and are sold in speciality stores and large retailers. The first time I recently saw a Nehi grape soda was in Asheville, NC in an old general store in a horse watering barrel full of ice and retro drinks. It was summer a few years ago and that ice cold Nehi took me right back to barefoot days on hot asphalt streets in the summer 50 years ago. Thanks for the post!
