Some pages about Paper Watermarks and its collecting
What is a watermark in paper? Watermarks are designs or patterns put into paper during its production, by making thinner (line or wire watermarks) or thicker (shadow watermarks) the layer of pulp when it is still wet. Hence, the name.
As any other thing, watermarks, or papers carrying a watermark, may be collected as a hobby.
COLLECTION: Some watermarks, from the collection of the author of this site. The classification is not definitive; will be revised as new images are added.
