This is a rare decor that uses a wellenoptisch (wave optic) ground with large applied silberiris tadpoles that in this case double as feet. The cut top is absolutely correct, and corresponds to PN II-5550, ca. 1908. The vase is exactly 13.5 cm tall, and glows brightly under black light. The last photo shows a series of Ausführungs in sequence - L to R: Ausf. 56, Ausf. 57, Ausf. 58, and Ausf. 59.
For more examples of Ausf. 58, see the decor page on Loetz.com here:
