The Whitehall Mural by Remigius van Leemput (1667) at Hampton Court Palace. Photo May 2015.
This is one of two surviving copies of the Whitehall Mural by Hans Holbein the Younger. The original was destroyed in a fire but we do have part of the preparatory sketch, which is held by the National Portrait Gallery. (Apologies for the glare and blur on the photo!)
