What does your comment even mean? If I were to create an original piece of art of an famous style, would that be considered a “blatant rip-off”? For a sanity check, here’s the website of the artist that created this original illustration: https://janneiivonen.net/about
You mean to say this fraud didn't even design his own site? Regardless, it's clearly ripping off of a well-known art style. Disingenuous to claim "deep, strong branding" when it's simply a cheap imitation. What a joke.
It predates Hergé. Bécassine did it two decades prior. It is so old that it will enter public ___domain next June (death of the artist + 70 years in France).
