I had the honor to visit Frans Snijders Blok in Bussum for the last three days. He has collected nearly ALL LEGO Minifgures. His collection is just amazing! He is also offering special sets and pieces at this online shop Blokbricks.
Today I visited Ruud Woeltjes, one of the founders of the Dutch LEGO club De Bouwsteen. He collects and builds LEGO models for already more than forty years and his amazing collection of LEGO bricks and models takes more than a whole floor in his house. He has more than a million bricks! It is the biggest collection that I have ever seen.
