Holland Casino - Diamond Days, May always brings all that birds-business but most of all... the Diamond Days at Holland Casino. You knew that of course but it seems that others don't know. Skipintro therefore came up with... a little film. The film was distributed far and wide across the internet and was obviously also on show on Holland Casino's own website. The film is directed by - keep the name - Lourens Blok from Caviar Amsterdam.
