There's also the original 1957-1964 TV show, Herge's Adventures of Tintin. Here's a fragment of its original airing on Catalan public television (TV3) during the 80s: https://www.youtube.com/watch?v=XMH76zya8MQ. That's seemingly the only available piece of that particular translated version on the Internet, and its audio is damaged, at that. Makes me think of how much content has been completely lost through the years.

OTOH I miss the "Tricycle-Dinamita" absurd comedy series both in Spanish and Basque. For HNers, they are almost like the Catalan Monty Python with a background from theatres.

I vaguely recall seeing this in the UK in the 80s and then being impressed with the much more authentic animation styles of the later cartoons.

Internet archive has it too https://archive.org/details/The.adventures.of.Tintin.animate...

As a kid I found it embodied quite fittingly the naive mystery of the comics, the direction, pacing, music .. everything was on point. (Something that was lost on spielberg 3d movie variant imo, too much indiana jones in spirit)

I agree. The cartoons felt literally like the comics brought to life.
