a <#stamp> printed on two layers of paper. There are two distinct causes of double paper: 1.) a double paper was intentionally used on some stamps by the <#cbnc=Continental Bank Note Co>. in the course of printing its <#largebn=Large Banknote> stamps of 1873. 2.) double paper resulted on some <#rotpress=rotary press> stamps when a tear or cut in the <#web> was repaired with a <#splice>. Splicing required some overlapping of the <#web>, hence creating a double paper variety. Double paper varieties were also created when two webs were attached to each other.
