There’s a nice set on the current comiclink auction(not my book).  I’ve been collecting the smurfs 1982 marvel set.  Cool covers on that set and they are cheap but that set came out 25 years after their 1st appearance.  Surprising I had one well known dealer on this boards not know what Spirou 1071/1072 were(not a bad thing but more indicative of the lack of a market for it). Do most dealers know about them? Maybe since there isn’t much demand at cons therefore it’s irrelevant all these years?
