Old-style copies refer to the traditional method of copying documents, which involves using a mimeograph machine. Mimeos, also known as mimeographs, are a type of duplicating machine that uses a stencil to produce multiple copies of a document. The stencil is placed on a drum and ink is applied to it, which is then transferred onto paper. This method of copying documents was widely used before the invention of photocopiers and other modern methods of duplication.
