Because it contains 78 cards it has also been regarded as a tarot deck.
The violet cards are numbered from 1 to 20 using the numbers printed in the bottom panel, although the top panels have a completely different order.
The unnumbered violet card which has no number could be construed to be the number 0 Fool card from a tarot deck.
There are no clues on the box.
