Found these lovelies today at a thrift store. I have a few friends that will be sooo jealous. You see, we are fans of a little known drink called the Moscow Mule. Proper Libation Etiquette reflects that they shall be served in a copper mug. Trust me, it is not the same without. Here is the recipe as made famous (at least in KC) by Harry's Country Club.
I found them for a delicious 69 cents each. I just did an ebay search for them....they range from $15-20 for 2. Score.
