It's not wrestling is it?
No, wrestling is derived from
to wrestle which isn`t ambiguous, as it has one meaning. While the sport in the photo comes from a name which is quite equivocal because its primary meaning concerns sth else. Hint - the name of an object used by people, especially by individualistically oriented Poles.
:( It's not anything to do with the Jewish Culture Festival is it
Sorry, no. I will show you the last photo from the series to help you guess. If you don`t solve it now, I give up. :)
So, again - what was the situation which encompasses the last 4 photos?
