Loetz Ash Tray, PN II-6339, ca 1909 for A. Rupp

Here is something you don't see very often - a Loetz ashtray! You sometimes see glass bowls with metal mounts meant to hold cigarettes, but here there are folds in the rim for this purpose. Cobalt Norma or Silberiris with interior silver iridescence. About 5" in diameter.
