Abstract

The invention is concerned with a device basically consisting of two sheets of paper, on the first of which the printing or writing is carried out and the duplication on the second. After completion the two sheets are made to stick together in off-set positions so that the duplication remains attached to the original and it is no longer possible to alter it.
