Around the end of the 19th century, Britain experienced a huge puzzle craze.
I managed to pick up a number of the famous puzzles during that period in flea markets, despite their rarity.
This puzzle is based on a puzzle that later reappeared in America, which we have successfully revived in its new form.
Keeping in mind the interesting idea that the “flags” should help you in tackling this one. I only hope you enjoy the final “release” as much as I do.
