I am not sure what is going on here. I’ve just found – on Amazon – both these images. The one on the left is the actual book cover; the one on the right I’ve never seen before. Leaving aside the colour variation which I’ve not tried to fix, there is quite a change in the text. I never really liked this cover, which always struck me as confused. The earliest version I saw had an even worse colour scheme – red and yellow, which I managed to convince them was the colour of fast food. That was the only thing they budged on. But the text positioning – which I asked to have changed – was always as the one on the left. So, where did Amazon get the variant from?
