I saw this exhibit of toys yesterday at Helsingin Taedemuseo in Helsinki called "Of Toys and Men." (The Finnish exhibit name is "Lelun lumo" which translates loosely as "The Toy Charm.") It's certainly great fun for all ages as it caters to both children and the inner children of adults.
I enjoyed seeing an over-sized fussball table customized with Barbie Dolls as players, lots of toy cars fit for the children of royalty (and from the looks of the exhibit "on loan from" lists, probably used by the children of royalty). And maybe my favorite part, a section of toy robots that appealed to my inner Doctor Who.
The exhibit runs through May 20th and is part of World Design Capital Helsinki 2012.
