It's all on the Pictures

18 cards are placed around a room where the guests can easily see them. The guests receive a score-card, on which they will write down their answer. The cards have an illustration which is a kind of illustrated cryptic clue. Under the picture is the item that guests must write down in their related answer. Card examples: Card 6. A close-up picture of a tree and the subject is 'Find the Misician'. Answer = Bach (suggested by the Bark of the tree) Card 17. A picture of a Shell oil can and the subject is 'Find the Seagull'. Answer = Petrel (the visual clue is Petrol) I told you they were cryptic! The first player to answer all 18 cards correctly, wins.
