Photograph of a white duvet with a series of narrow pointed ridges/folds reaching into the distance (my legs beneath the covers). It looks, not really but a bit, like the iconic sound wave illustration on the cover of the famous Manchester band Joy Divisions album Unknown Pleasures.

Cover art for Joy Divisions album Unknown Pleasures. A black background with a series of white lines that form peaks, like a narrow mountain range, but which are in fact an illustration of sound waves.
