King and Queen of Hearts Mug

Vintage mug with king and queen of hearts design. The handle is shaped like a heart. There is manufacturing information on the bottom, but it is incised so shallow, as to be impossible to read. The height is 3 1/4 inches. No chips, cracks, breaks or rough rim, but has a tiny dark mark on the handle and several manufacturing flaws. I need your zip code to calculate the postage.
