The Piccadilly branch of the UK bookseller Waterstones spoofed E. L. James and Fifty Shades of Grey, creating an eye-catching display of titles from Persephone Books–the sleek covers all decorated with the same “One Shade of Grey.”

We’ve embedded a photograph of the display above, it reads: “Oh the bliss of Persephone Books! Beautiful editions of titles by neglected female writers.” Persephone Books is a UK publisher that releases both fiction and nonfiction. You can explore their catalog at this link.

Here’s more from the publisher: “Waterstones in Piccadilly has become our new favourite shop ever – totally without telling us they have done this fantastic display – very many thanks to cathyreadsbooks for taking the photograph. For weeks we have resisted making comments about really good grey books as opposed to really not good – ‘One Shade of Grey’ is a far wittier way of doing it.” (Via.)
