These embossed Vernor's bottles have no dates on them but date to the early 1900s. They are the first to use crown caps. The earliest ones in use had ceramic stoppers with wire bales.
By 1918, Vernor's had adopted the motto, "Detroit's Drink", which was embossed on the bottle's shoulder along with Vernor's Ginger Ale and also used paper labels. In the '20s, the motto was changed to "Deliciously Different", still using the shoulder embossments and paper labels. There are some manufacturing #s on the heels of the bottles with the capacity embossed after that became necessary by law in 1913.
These bottles all have Vernor's Ginger Ale and his VGA logo on the bottom, because they were stacked in the cases upside down to keep the corks wet and not lose the carbonation.
The Vernor's collectables in the glass case pic submitted by SODAPOPBOB belong to Keith Wunderlich, who is "Mr. Vernor's" and had a nice book published by Arcadia of the history of Vernor's. Lots of pics and a good read.
Thanks for the great pic and info. Do you happen to know anything about the plain looking (apparently non-embossed) bottles like the one in this ad that has a paper (non-gnome) label?
Wunderlich's book has a tray with your image on it. The lower end, cut off in yours, says "Detroit's Drink". He dates it to 1918.
My bottle below has heel marks 20 S 2. I believe it once had the paper labels shown. Never seen one though.
