Captain Jupiter is too recent I think but I'll check again. A lot of the Dutch comics are reprints of newspaper strips and I believe the copyright still resides with the newspaper publishers. There are many official reprints of some of these strips on sale.
Martin Toonder material, while excellent, is too risky for us.
I'll dive into the section when I get a chance. There are some gorgeous strips and they are available on certain sites.
Indrajal and other Indian publishers confuse me. A lot of titles are KFS reprints but there are a number of home grown titles and characters, mostly relatively recent, ie, post 1960.
Also, while I read French, Italian, a bit of Spanish, and can sort of get the gist of Dutch as long as there are pictures, Indian languages completely defeat me. And as many comics are not in English, I'm stuffed.
If anyone wants a bit more info, send me a pm.
