This large oil flask (large alabastron) is a Corinthian shape and is painted in a black-figure style which looks similar to Corinthian and Athenian decoration, but the clay suggests that it was actually manufactured in Boeotia. It shows a standing siren and a flying bird with rosettes in the background, which is a design typical on Corinthian vases.

Ure attributed this to the work of the painters of the Horse-Bird Group, which Beazley believed were all by the (Athenian) Painter of the Dresden Lekanis, who was Athenian. He suggested that the Attic vase painter emigrated from Athens to Boeotia.
