An Experiment with Covers

I have in my library a number of old paperbacks with rather fine covers. These do not depict directly the contents of the book, but are rather patterns, abstract or otherwise. Here is one of these.

Now, you will note that this is the back cover, lacking the title. I wonder if those seeing these for the first time can identify the writers or subjects or time periods that these books discuss just by seeing these characterful covers. So take a look and put your answers in the comments.

I shall say that these are all volumes of poetry, generally by English-speaking authors, largely from after the 16th century.

It would be wildly optimistic of me to expect that you will get it spot on. But it will be interesting to see how close you get.

These last two have price labels printed as part of the cover.
Could this be of any assistance? Who knows!
