What's black and white and red and weighs just half a kilo? Mediokilo, the compact compendium of icons and vignettes from HB Design Studio in Buenos Aires. Icons for the sun, the tragicomedy, a hammer, a microwave oven, a book, a peg, a carpet, on the rocks, an altar boy, a conscience laundry, an obelisk, a cold buffet, a martini, a suitcase with a lock, an armchair, a spool of thread, crude oil, and many, many other items and expressions that merit their very own pictogram for a world of wordless communication.
