Decorating the Christmas Tree December 1944 Marlag O by John Worlsey. ‘Lieutenant Houston Rogers playing the whistle while behind, decorating the tree, is Lieutenant ‘Blondie’ Mewes, RNVR who had tried to escape the first time “Albert RN” (a mannequin) was used’ (Imperial War Museum). There is another John Worsley painting, possibly of the same room at Marlag, here.
