Sprinkled paper

This particular example of sprinkled paper was purchased in London some years ago. When purchased, it was already several decades old. It is clearly of a kindred nature to a trickled paper already featured here The paper is a cloudy pattern, made in gray, green and red. The paper itself is deteriorated and brittle.

Papers of this sort remind one of the papers manufactured by Edward Seymour's Fancy paper company. Perhaps it was made by that institution?
