Didn’t see it (obviously), but I think it is a very good idea. I’m all for openness in showing the goyim who we are and how we live. Nothing negative in that. Helps to reduce anti-Semitism, reduce misunderstandings, increase respect.
Doesn’t have any negative impact on the children anyway – I mean, they see non-Jews on the streets and in the supermarkets as well, and on vacation, so there’s no argument there.
