front and back
this modular system was designed by ugo la pietra for berdonini in 1967, and re-issued last year. it uses slotted, stackable elements to create an extremely unique two-sided bookcase with the straightforward logic of a folk solution. at first glance it seems a little bulky, but a longer look at the design shows it to be virtually irreducible, which is the essence of minimalism. while i'm sure there's nothing "minimal" about the pricing, this seems like very good thinking for a basic but stable stacking system. the single-file stack [at top] would be a great space-saver with the flat side pushed against a wall.
