Hi Linda, all your images could be used as bookcovers. If you were to make one of these a book cover say for MIT Press, in order which one would you choose? What 2-3 lines of text would you give the designer to interpret the image into the main parts of a bookcover, i.e. which image, with what style of typography (handwritten - look at the designs of Stefan Sagmeister, helvetica or something else) what colour would the text be in complement or in contrast to the image?
If you had to go with a press that gives you pre-designed book covers like the Pivot range, what colours and patterns would you go for, what 3-4 keywords would help you to make that decision? Here are some already published: https://www.palgrave.com/gp/campaigns/palgrave-pivot
