This vintage double egg cup covered in strawberries is most likely from Japan. I have not been able to identify the pattern or company. However, the yellow trim with the three vertical bars every few inches is the same design that is used on Japanese PY's Rooster and Roses pattern.
The egg cup stands about 4" tall and measures 2.75" across the large cup, and almost 2" across the base. It has overall crazing with slight browning on the interior of the cup. There are two extremely tight hairline cracks, one of which is only on the outside. Both are very hard to see unless examining closely under bright light, and should not affect its function should you choose to use it..
