Numismatists, unite! These are illustrations featuring Churchill the Polar Bear and his woodland friends in their childhood (before they were featured on Canadian coins like the twoonie, nickel and quarter), sliding down a magical tree. These are lenticular coins, meaning that the full-colour images flip back and forth as the coin is tilted.

A mini-feature on CBC’s website here (and yes, I know I said “loonie” instead of “twoonie”…!), as well as a radio interview here.
