This is a set of four pot de creme cups produced by Wedgwood. The color is classic green with white raised trim typical to Jasperware pieces. The lid has a star burst pattern radiating from the final outward to the edge of the lid. The finial is a simple knob style.
The pattern on the cup is leaves with little cutouts that start at the bottom of the cup and reach upwards to the widest part of the cup body.
The pot de creme set was manufactured in England and is dated 1979, see the mark image from the bottom of each cup.
