Haight & OBrien St Louis Mo (Rather than underlines, they're 2 dots each).
I'd always wanted a pontiled squat that is embossed, since I found out what they were.
Amusingly, I picked it up only for resale. LOL. (If interested, make offer in P.M. or email).
So, here is my first pontiled pop/soda/water/beer? (I've not done historical research on it as of yet).
