Extremely unusual and no doubt rare double deck of “Metri-Magic” cards, created c.1977 by Michael Shwarger for LaPine Scientific Company. They are designed to teach the basic concepts of the metric system through card games. I am skeptical, and doubt that they met with success. Frankly, I am reluctant to describe them as “playing cards,” but the booklet that accompanies the cards explains the deck and how it can be used to play games. It contains the rules for a number of games, and makes the claim that poker, rummy and bridge “can be easily be adapted to the Metri-Magic deck.” Given that the deck has 6 suits with 8 values in each suit, I have a hard time imagining an “easy adaptation” of bridge, but I confess that I have not made the effort.
Each deck has 48 cards, described as follows: “The ranks of Metri-Magic consist of eight most widely used prefixes of the metric system: milli, centi, deci, one, deka, hector, kilo, mega. The suits are made up of six units: metre, square metre, cubic metre, litre, gram, and watt.” In addition, I note that there are 6 identical Metri-Magic Reference Cards. Perhaps these cards serve as Jokers, or something similar. The backs of both decks are identical. As noted, there is a 32 page booklet describing the cards and the games that can be played. The cards are bridge size, measuring 89mm x 57mm, and the cards and booklet come in the original hard plastic box.
One deck is mint and sealed. The other deck is mint, removed from its wrapper to be inspected and photographed for this listing. The box has slight wear, but is otherwise without issues.
Thanks for visiting.
