Gotta hand it to Worcester Soda Company, they made very drinkable soda/tonic/pop products and had a few interesting bottles for the stuff to add to the thirst quenching. Even though this is a mere clear bottle it's loaded with design aspects that make it stand out. I suppose you can see this a bit more around the New England area, but I live here and I don't recall seeing this one before, and I'm no spring chicken. I'm sure a bunch of Worcester-ites will chime in...but this one's a bit unusual, consider adding it to your cool stash of soda bottles.
So ok, not that I am the expert to put to words what the design elements are, so I'll let the pics do the talking. It's clear glass so I hope I have done the pic stuff well enough for y'all to get a good idea. See those pics they (attempt to) tell the story. Please email if any questions or comments.
