First Crock Bottle

I am way excited.  Today I found my first ever crock root beer bottle.  Dr. Swett's.  Found this in one of the Denver Antique Malls on South Broadway. I have been looking for one of these for many years.  Of course you can buy them on eBay, but I prefer the hunt. My thanks to whoever put this gem up for sale.  This is from the 1890s. Now one of my choicest treasures.
