Well basically they're all Eurocine WIP type exploitation flicks and there's some hard to find cult titles like Helga Shewolf of Stilberg.
Btw picture quality is as good as the masters in Eurocine's vaults allowed and an effort has been made to offer the most complete versions.
All these (except Convoy) were released on French dvd (French language only) some time ago with 1 dvd retailing at the price of this whole box.
Here's a review of the French dvd of Elsa and Special Train (with screenshots),the Dutch dvd's should be similar.
