Abstract
A business form, which may be a tag, label, ticket, identification card, or the like, comprising a base sheet adapted to receive writing or printing and a transparent sheet having adhesive by which it can be laminated to the base sheet, and a liner sheet covering the adhesive. A removable carbon paper or other sheet lying between the liner and base sheets is secured to the former whereby removal of the carbon sheet automatically causes the liner sheet to be pulled off and removed and the transparent sheet to be applied to the face of the base sheet.
