I collect comics (all kinds, but mostly Flemish ones and all of Dupuis Editions) and comic related stuff, and books (SF, fantasy, some juvenile, everything by Flemish illustrator Demoen, everything by writer John Flanders (aka Jean Ray)), and Mike Oldfield records. I try not to collect anything else, although I often think of something that it would make a fun and not too expensive collection (like those hitcollection records of the seventies, by companies like K-Tel: collect all those records with semi-nude or semi-sensual ladies on the cover, and you have a truckload of real seventies culture
).
