Hi,
Never in a million, is this original. The vase matches the frog, or the frog and figurine go together, but missing the bowl. Not all three.
I will take some time tomorrow, and hopefully find the origin of all these pieces, but the vase has come from either Stolzle or Niemann Stolle, as this pattern was made by both companies.
Regards,
Marcus
Vase, if Stoelzle is pattern number 19116 - 10 inch
