Minimalism to Constructivism

One of the sweet objects in the Modernism show at the V & A, London, right now:
Nikolai Suetin's Cup and Saucer. Black Cross and Circle, 1923. Malevitch's Black Cross, now at the Centre Pompidou, was painted in 1915. (I've had the postcard, below, by my bed for years).
Minimalist or Constructivist? "Suprematist", in fact. There's actually a huge difference between these two artifacts, showing the minimalising/reducing of Malevitch's Suprematist black square on white plaster, and the constructing/adding/composing in the Constructivist design on the cup.
