I had a great find at the car boot sale on Saturday - a big box of Which? magazines from 1960 to 1981. There are a couple of years missing and quite a few of the 'Money Which?' and 'Motoring Which?' supplements are missing, but as a collection they are well worth the £10 I paid!
Above are a selection of the covers, they are really great, I personally prefer the more graphic ones, but there are some more photographic and also some which are more illustrative. They are quite text heavy inside, but remain clean and un-cluttered, with some lovely typography. Also because of all the comparisons and tests that they run, almost every issue has a really well-designed chart, graph, diagram or illustration making them valuable reference.
I will eventually scan in all the covers and create a 'Which? Covers' Flickr group, so watch this space!
