We went to Disney Land 2 years ago and I hadn't been in decades. Nostalgia is a strange thing, it's hard to explain. But going through the It's a Small World "ride" just made me smile and warmed my heart. I loved it as a kid-- and still love the message it sends.
I don't think these would have to go in a kids room (although I'd love to put that first blue one in Reece's room!)-- I would have these out where everyone could see them. They look so modern and fresh.
Above are all prints that can be bought as a canvas here.
