Man's Best Friend is our collectible commemorative bill to recognize dog lovers everywhere. The animal pictures on the front and the back of the bill are of cuddly, lovable dogs. Dogs, the first animals to be domesticated by man, reportedly descended from their wolf-like ancestors and have truly become a loyal companion to man, hence Man's Best Friend. The bill's denomination is "K-9 Dollars," and the verbiage on the front of the bill is Furry Friend, Bow Wow 2002, and Woof Woof 02. Whether your pet speaks Bow Wow, or Woof Woof, you are sure to enjoy these beautiful novelty animal pictures bills!
