EO Wheel caricature, 18th century caricature of men gambling on an "E.O." wheel (or even-odd wheel), a precursor of roulette.  There is a ring of smaller "E" and "O" letters running around the outside of the ball area (inside the outer two rings of large "E" and "O" letters, which are for placing bets), but the inner ring is not really distinguishable in this image version.
