...will surely tempt the solver into assuming that the picture is anachronistic -- containing artifacts that belong to some time in the past. Here we see Fuzzy Dice, which went out of style decades ago, dangling from the rear-view mirror in a photograph surrounded by datable objects seemingly too recent for contemporaneous depiction. Indeed, all of the first four choices might be said to meet the criterion for being "wrong"; however, the puzzle instructions said, "Choose one."
Accordingly, we must conclude that the anachronistic assumption
is wrong -- that instead, the photograph is merely modern enough to include
everything in it. The solution can only be...
So what is it?
bserve that the Fuzzy Dice in the photgraph are not identical. The die on the left has its visible pips arranged in the order 4-5-6 clockwise around the closest common vertex. The die on the right has 4-5-6 in a counter-clockwise arrangement.
Since antiquity, the tradition for ordinary dice calls for opposite sides of each die to total seven (1+6, 2+5, 3+4). Moreover, it must be possible to place two dice together in a position such that all pairs of pippings -- opposite sides, side-by-side sides, and even facing sides -- sum to seven. The sketch above shows how that is accomplished by two identical clockwise dice.
Juxtaposing a clockwise die with a counter-clockwise die will not achieve that effect, as the sketch on the left illustrates.
All those summings-to-seven merely mandate a minor matter
of mathematical magic. Ah, but tricking up your car with Fuzzy
Dice was for a long time considered a tasteful visual improvement
for cars as well as a good luck charm (despite interference with the driver's
visual field) -- a talisman
undoubtedly assuring success in vehicular romance more effectively than
an ugly old rabbit's foot.
This souvenir coffee cup turned up on the kitchen shelf of a certain puzzler and is presented here for solvers to ascertain what is wrong with the illustration.
Hint: The name on the cup is not wrong.
