20 000 Lieues sous les mers - Jules Verne

This is a French collectible note issued in tribute to Jules Verne's 1870 novel, not legal tender — part of a series celebrating French literary heritage through banknote-format souvenir pieces. The printer, Státní Tiskárna Cenin in Prague, has produced security documents for dozens of countries since the late 1920s and is a credible choice for a collector-grade item requiring watermark integration, though the pairing of a Czech state printer with a French cultural subject is purely commercial.

Designer Matej Gabris has worked on several notes in this French literary series. The watermark is the sole listed security feature — modest for a modern production but consistent with the souvenir note category.
