This is the Polish dance, "Krakowiak".
The beginning pictures are not from the Dance Show.
These show the beginning of the dance (with one of the babies watching)
and the most difficult figure of the dance, the "box".
These are the heel-tapping part and the polka.
These are from the Dance Show. They show the open figure
and the "brush".
These are the figures with the jump-and-stamp.
And this last is another picture of the difficult "box"
