In 1967 Danese debuted Enzo Mari's Il Posto dei Giochi, The Place of Games, otherwise known as "Wall." Kids could use the ten-panel corrugated cardboard play structure printed and perforated with Mari's designs to create various kid-sized spaces.
The only drawback, of course, is that it only worked if you were a kid in 1967. Wall has been out of production for decades, and when I came across it last year, I had more than half a mind to design and produce a new Wall. Well, I'm sure glad that knockoff scheme didn't pan out. Because Il Posto dei Giochi has just been reissued by Corraini, which, like Danese, also has a longstanding relationship with Mari. Wall is part of a series of kid-related reissues from Corraini. [Well, three. The other two are book/things by Bruno Munari.]
Corraini's version of Wall is even awesomer than Danese's, though, and not just because it exists: it's in color, unlike the original, which was printed in black and white for black and white children. Apparently the whole country was like that. True story. Lasted until the 1980's. Benetton ads.
