I think this is a fantastic cover design. It was printed in Moscow in 1966 – a geometry textbook that somehow found its way into the collection of the San Francisco library where I work. Not surprisingly, I am the first person ever to check it out. One of the things I like best is that the typography is so retrograde. It looks more like the 1930s than the 1960s. I suspect in terms of style the High-Stalinist industrial look tended to persist in the Soviet Union right up to the collapse of the Empire.
