An oil sketch attributed to Etty , given to York Art Gallery in 1952 by Judith Hare , Countess of Listowel and entitled Three Female Nudes , is possibly a preliminary study by Etty for Youth and Pleasure , or a copy by a student of the three central figures . Art historian Sarah Burnage consider both possibilities unlikely , as neither the arrangement of figures , the subject matter or the sea serpent approaching the group appear to relate to the completed Youth and Pleasure , and consider it more likely to be a preliminary sketch for a now @-@ unknown work .
