Please help: Need information about old German Fipps doll

Hi

I'm from Denmark and collect some old toys, mainly slot cars, toy cars and
model trains and stuff but I don't know much about dolls. I have just got a
few dolls. One of 'em is a pretty old doll (pre-war I assume). It has a sign
that says "Tanzpuppe; Fipps; ges. gesch.". I assume that Fipps is the name
of the manufacturer. I would like to know the following about this doll:

1 - When was it produced ??
2 - Is it a common or a rare doll ??
3 - What's the approximately value of these dolls ??
4 - What's the English name for this "Tanzpuppe" doll ??

Here is a link to a picture of the doll:

and here is a close-up picture of the "Fipps-sign":

Thanks for reading my message - any help will be highly appreciated !!


Sincerely,
Mikael Gitt
