Greek Corinthian black figured pottery pitcher

I know NOTHING about this wonderful little vaseother than it is a Greek Corinthian style done in the black-figured technique. One side is the bust of a person, and on the other side is a leaping dolphin. Measures just 4" tall and is in perfect condition with no chips or cracks. Actually looks thousands of years old, but has a lead tag that states EXACT COPY. The hole at the top is small so was probably for special oils or something. A wonderful piece.
