Abstract: A credit card carbon copy defacer in the form of a unitary device of relatively thin, stiff material, such as plastic or metal, having a first generally rectangular flat base portion dimensioned to fit in a billfold or shirt pocket of a user and an integrally, generally rectangular, flat portion folded along one edge of the base portion to extend generally parallel to and spaced slightly from the base portion so that a carbon paper may be received between the flat portion and the base portion, the base portion having one or more openings therein and the flat portion having protrusions in alignment with the openings so that when a carbon paper is positioned between the base portion and the flat portion and the portions manually pressed together, the part of the carbon paper at the openings is defaced.
