Cup with cover

The image is a grayscale photo of a Cup with cover by an unknown artist. The cup has a rounded body with a short cylindrical foot and two small handles on either side. The cover is dome-shaped with a short cylindrical protrusion on top. The body and cover are both decorated with an etched design featuring leaves, flowers, and possibly a dragon or snake. The design on the body appears to feature a large leafy branch. The background of the image is solid black. The cup is positioned centrally in the image. The cup and cover appear to be made of a smooth, possibly ceramic or glass material. The number 489 is written in black on the front of the cup.
