I think this is the 'Verzamelbeurs' (Collectors' Fair) which is held in Utrecht two times a year, and which always has a fair amount of vintage and modern Star Wars and actors doing autographs. Also a lot of other collectables (comics, vinyl records, coins, ....almost anything)
It is organized two times a year (April and November).
I will certainly go there. Would be great to meet some of you there.
I am always going to the Verzamelaars Jaarbeurs both editions. Like Dr Dengar said it is fair ( the biggest in Europe) of everything you can think of too collect. Do not expect to find lots of vintage Star Wars there, but every now and then there are some gems to be found.
Would be fun too meet up with other collectors there. Last time in november there were plans to meet up there and only me and one other collector showed up
