The Victoria and Albert Museum has most amazing resource for finding unusual and varied prints, which you can view and order online, at V&A Prints.
There are a LOT of prints – something to suit every taste. I’ve chosen a coupld of favourites here, but there’s heaps more, under categories like Chinese Art, Flora and Fauna, Ikats, Landscapes…. And there’s even a clever categorising function that allows you to browse by colour. Definitely worth a look.
