Young people whose shadows are on the wall of the National Portrait Gallery in Trafalgar Sq, London. The two young men have been busking in this famous London landmark, their act having just finished requiring them to change back into their own clothes on a winter's day. One of them squints into the sun, making a definite shape alongside his sidekick and an incidental woman, texting on her smartphone on the right. A couple hug each other above as someone else takes their picture with Westminster in the background. The wall belongs to the southern frontage of the National Portrait Gallery in Westminster.
