The term master of puppets means that someone is very good at the controlling an d directing of puppets. another term would be puppet master. this is the way we say it in america.
Even though there's a question mark at the end of the string of words, this is not a question. Please restate the question.
There are puppet stores. But there is a place called zoom in Kansas city, it may be a toy store but has AWSOME puppets!!. And then there are a whole bunch of websites that sell full body puppets. Try Allpro puppets or Axtell, they are one of the best.
I can" recall any- maybe you are thinking of animated Robots who sometimes accomnpanied Jazz pianist ( Ragtime- high speed stuff) Jo-Ann Castle. Tiger Rag, that sort of thing. Puppets were used on the Ed Sullivan show ( notably Topo Gigio) and as a sort of side act on many variety shows-- the Muppets for example. But they were not used on Lawrence Welk. The only non-musical act was the monolog artist Aladdin.
