The Magic Square Impregnated (old matchbox label)

This illustration is featured on the label of an old matchbox, manufacturer unknown. This one states "MADE IN ENGLAND" across the bottom, and I found some mentions indicating that it was produced circa 1930.

I also found, while searching online, some nearly identical labels, the only difference being that they state MADE IN SWEDEN instead of England. Another, even more specially, cites Jönköping, Sweden.

"Impregnated" refers to fact that the match heads are impregnated with chemical fuses that allow combustion to take place if they are struck in the proper manner. Matches are further referred to as either safety matches (as these were) or strike-anywhere matches.

As far as the wizard and the Magic Square, Lars G. Wallentin of the Packaging Sense website called these the Sudoku of the 1930s:

"As each match box contained about 60 matches, The Magic Square told this in a very creative way. Note that however you add it up, whether vertically, horizontally or diagonally, you arrive at 60!"
