[E, O, or the fashionable vowels] [graphic].

"Gamblers seated and standing round an E.O. table. The table is octagon-shaped, the circular roulette mechanism being sunk in its centre, surrounded with the letters E.O. for even and odd. In the foreground (right), in profile to the left, a man leans back in his chair asleep, an empty purse on the table beside him; he resembles Captain Topham. The others are probably also portraits, but are more caricatured; they watch the table with gestures and expressions of anxiety and despair. There are fourteen figures."--British Museum online catalogue, description of lettered state
