Why yes, I do judge a book by its cover

I'm a big fan of BuzzFeed Books (and you should be too) and I just now got around to looking at 34 of the Most Beautiful Book Covers of 2015." As promised there are 34 stunning covers, although the one I liked best was this one for Satin Island by Tom McCarthy. It was designed by Peter Mendelsund, He's also done some stunning covers for New Yorker Magazine, and his work is elegant, minimalist, classy, timeless. He's also a writer, and his book, What We See When We Read, is a book that's now on my TBR--a study of why words evoke images.

I thought thr Satin Island cover was so gorgeous I looked the book up and to my surprise, there's a totally different cover on the book listed on Amazon. It's the one below left. I thought that was odd, but decided it must be a variant cover for a foreign edition. I checked on Amazon.co.uk and found yet a third cover.It has something of the watercolor feel of the original cover I saw and I like it better than the first variant but I don't like either as well as the cover that was used in the BuzzFeed article. I have to wonder. Was the publisher doing A/B testing with the cover?

I know which book I'd pick up first. How about ou?
