These 3 I got from a guy that found my blog. The center one is dated 1876. I am not sure how old the others are but likely prior to 1900.
These are all Hires. Some of them only have Hires embossed on the bottom of the bottle.
I friends called me the other day and told me about an Old Dutch Root Beer Thermometer at one ofthe antique stores in Lafayette, CO. I went to see it and picked it up. It was priced quite affordable.
And lastly here is an updated picture from the doorway of my root beer room.
Keep those emails coming.
