This was designed in 1973. Another brilliant example of old book design. The blog I found this on - bookworship.com - alost criticises the type by calling it 'over the top' yet it admires how this was created in the time it was designed. I personally love the type on this book. Anything repetitively linear appeals to me - particularly if it is very relevant to the design. I have no idea why. Just a case of preference I guess.
