The opening of a new location in Osaka, Japan, was occasion for luxury retailer Louis Vuitton to ask Italian design studio Happycentro to produce an appropriately elegant invitation card.The result was a printing and folding tour de force involving offset printing, transparent, silver mat, pearl and rainbow foils, dry embossing, silkscreen and die-cuts. As if that wasn’t complicated enough, the square sheet was precisely folded by hand origami-style 34 ways. One has to believe that the designer Federico Galvani has a fiendishly clever mind to devise something that tested the skills of printers and origami artists alike, but the team pulled it off and the result is lovely and unique.
