Problem picture
A problem picture is a genre of art popular in late Victorian painting, characterised by the deliberately ambiguous depiction of a key moment in a narrative that can be interpreted in several different ways, or which portrays an unresolved dilemma. It has some relation to the problem play. The viewer of the picture is invited to speculate about several different possible explanations of the scene. The genre has much in common with that of book illustration, then at its most popular, but with the text belonging to the illustration omitted. The genre began to emerge in the second  half of the nineteenth century, along with the development of book illustrations that depicted "pregnant" moments in a narrative. One of the earliest problem pictures is John Everett Millais' "Trust Me", which depicts an older man demanding that a young woman hand him a letter she has received. Either character might be uttering the words. The significance and content of the letter is left to the imagination. Their relationship is also unclear; in view of their ages, they might be a married couple, or a father and daughter. Other artists who worked in the genre included William Frederick Yeames, whose  And when did you last see your father?"" became the most famous example of the genre. It depicts a young boy of the English civil war period being gently interrogated by Cromwellian troops who are looking for his Royalist father. It is implied that they are asking a trick question designed to discover his location. The painting is poised at the moment the child is about to answer. Yeames painted many other works of this type, including "Amy Robsart" and "Defendant and Counsel". When the latter was exhibited a newspaper ran a competition for readers to guess what crime the  woman was accused of. Some avant garde artists also experimented with the genre, notably Edgar Degas and his follower Walter Sickert. Degas's "Interior" (1869) depicts an ambiguous scene suggestive of sexual transgression and violence (hence the alternative title of "the Rape"). Similar ambiguity is found in Sickert's "The Camden Town Murder" (1908), in which the two figures can be interpreted as a couple, or a killer and his victim. The genre continued to be popular into the early twentieth century, but was by this time increasingly seen as old fashioned and as over-literary, against the emphasis on  pictorial style and form characteristic of impressionism and post-impressionism.
