Red Valentine Typewriter by Ettore Sottsass & Perry King for Olivetti Synthesis

Designed by Italian Ettore Sottsass and Briton Perry King, and launched in 1969, this was probably the most famous of Olivetti's typewriters. Shown here in its signature bright red it, it was also produced in white, egg yellow, blue and pea green. It came with a slide-on case that ingeniously fastens to the back plate of the typewriter with rubber straps. Unfortunately, over time these would often dry out, crack, and break off.
