Published in Punch in 1933, The Art of Bidding shows nine heads captioned Some do it by raising an eyebrow, Some by the slight inclination of the head, Some with a wink, Some by adjusting their tie, Some by elevating the catalogue, Or a forefinger, Some by the removal of their spectacles, Another by replacing them, But the heathen – does it by word of mouth.
