A man and woman are so drunk that they are unaware they are being robbed. Their foolishness is underscored by the print on the partition. It depicts an owl, considered a stupid creature in the 17th century. After all, it could not see by day, not even with a candle or eyeglasses. The drunken couple is thus just as blind as the owl, a message that survives in the English idiom ‘blind as a bat’.
