I particularly like the autumnal cover - orange and brown are the classic 1970s colour-combination.
The "Computer Education" cover totally represents both the enthusiasm and fear in the context of computers at the time (and partly still today). Rainbow brainwash?
I find these covers to be fascinating - the magazines themselves deal with very technical industrial computer programming (the sort of machines you see in archive film with whirring tape spools and banks of flashing lights). Yet the covers themselves are much more forward-looking (and somehow of their time too - I agree re the orange and brown!). I also agree re the 'Computer Education' cover - interesting that Frank Yanai chose an old phrenology engraving in juxtaposition with the computer-age rainbow.
Fascinating and beautiful indeed. And, right, phrenology, I haven't noticed first. It's another thing you'd probably avoid while talking about education nowadays...
I do like the Operating Systems cover. A very fine collection.
