Back in post #21 I said "Not", but later I remembered the one instance where I bought a book on the strength of its cover. I had seen Dick Francis books about for ages, but as I wasn't the slightest bit interested in horses or horse racing I ignored them. (I once outraged a horse-loving niece by explaining that horses were just a handy way of keeping dog meat fresh until needed...)
Anyway, one day there was this paperback:
Well, as a photographer ever since I was old enough to push the button, and who has owned and used everything from a box brownie to a 4 inch x 5 inch studio camera, and now run a Nikon SLR digital, I took a punt on a book with a camera lens on the cover.
It was a good book, too, and I have read every Dick Francis up to his last. I still have the same paperback.
