Leprechaun character jug modeled by William K. Harper and produced by Royal Doulton of Burslem, England, between 1990-1996. A leprechaun is a diminutive supernatural being in Irish folklore, classed by some as a type of solitary fairy. They are usually depicted as little bearded men, wearing a green coat and hat, who partake in mischief. In more recent times, they have been depicted as shoemakers who have a hidden pot of gold at the end of the rainbow. A rainbow with sack of gold at the end forms the handle of the jug. The Leprechaun character jug was made in two sizes with this being the largest along with small (D6899) size.
