Loetz Rosa PG 2/484 (Medici), PN unknown, ca. 1902

Although Rosa in German translates to "pink", this example comes out on the dark end of that spectrum, owing perhaps to the liberal spraying of the chemicals providing the exceptional iridescence. Thanks to Andy for finding this one, and allowing me to pry it from him. :)
"Pink Medici" is one of the harder to find colors of this decor, also known as Phänomen Genre 2/484. The shape for this one is probably lost in the black hole of paper patterns from around 1902 that did not survive - it stands 12.5 cm, or about 5" tall.
