Theme collections are collections consisting of different type of objects with a common denominator or theme.
These collections go beyond the usual object classifications we use here at Collectioseum. The theme collections are about a common theme, not common material or type of object.
Just to give you an example: Star Wars is mainly a movie franchise. In our theme collection for Star Wars you won't, however, only find movies but also action figures, books, movie posters and other tidbits connected to the epic franchise that is Star Wars.
