How is the UN Security Council like a small mall in Tokyo?

This makes me wonder what other public places have Guernica on display. One is the city of Guernica. I used to walk past the tapestry version at the United Nations every day. And this is in Oazo shopping mall near Tokyo Station and the Otemachi Chiyoda station.
It's painted on ceramic tiles. There's a typo on the sign next to it: the Japanese version says the original was painted in 1937 and the English puts it in 1973. I'd love to know why this was chosen for a lounge that has flowers and dragonflies embossed on the manhole covers.
