Book - Brass Rubbing
Brass rubbing was originally a largely British enthusiasm for reproducing onto paper monumental brasses – commemorative brass plaques found in churches, usually originally on the floor, from between the 13th and 16th centuries. The concept of recording textures of things is more generally called making a rubbing. What distinguishes rubbings from frottage is that rubbings are meant to reproduce the form of something being transferred, whereas frottage just desires to use rubbing to grab a random texture.
