I somehow thought that the stamps where you can see the lines/fibre direction at the back were generally cream paper. That may be completely wrong or stupid as the catalog does not mention a different production method, but rather that a different quality of water was used in the production process of the paper. Otherwise, it's not that easy to distinguish. I would love to hear from a specialist...

Cheers,
Joel.
