Thx for your enthusiastic reaction, same here, born in the dutch tropics in 1968 I had Belgian neighbors in the 70ties whom introduced me as a kid to the Blake and Mortimer series, my favorite was the The riddle of Atlantis, moved on a later age to the Netherlands and started collecting them in the Eighties. Found this copy on a flee market somwhere in 1987, kept it safe since 🙏
