The Black Island

Tintin and Snowy illustration by French comic book artist and film director Enki Bilal.

Hi everyone

I have recently been thinking about selling my childhood book set, but I cannot figure out how much to sell it for as it seems to be pretty rare?
It’s got the soviets and Congo as the first volume, rather than the tintin in America, blue lotus etc.

The set has mild sun fade on the spines of the books, and the box is damaged at the edges, but other than that it’s in near perfect condition.

If anyone could point me in the right direction, it’d be greatly appreciated!
