5.K.1. DERANGED BOXES OF A, B AND A & B
Three boxes contain A or B or A & B, but they have been shifted about so each is in one of the other boxes. You can look at one item from one box to determine what is in all of them. This is just added and is certainly older than the examples below.
Simon Dresner. Science World Book of Brain Teasers. 1962. Op. cit. in 5.B.1. Prob. 84: Marble garble, pp. 40 & 110. Black and white marbles.

Howard P. Dinesman. Superior Mathematical Puzzles. Op. cit. in 5.B.1. 1968. No. 26: Mexican jumping beans, pp. 40-41 & 96. Red and black beans in matchboxes. The problem continues with a Bertrand box paradox -- see 8.H.1.

Doubleday - 3. 1972. Open the box, pp. 147-148. Black and white marbles.
