Abstract: The invention relates to a multiple part recipe card kit and method of construction and use of duplicate recipe cards. The recipe card kit includes a plurality of superimposed, coextensive, carbonless recording sheets in combination with a plurality of water-resistent, transparent laminae corresponding to the number of the recording sheets. Each of the recording sheets has a face. The recording sheets have a common joined border and are separable from one another proximate the common joined border. The recording sheets contain pressure-sensitive image-transferring chemicals which allow the recording sheets to receive recorded information simultaneously upon each face when the information is inscribed on the face of the top sheet. Each of the laminae are of sufficient size to completely overlie the corresponding recording sheets. Each of the laminae has a first side. Each first side of the laminae has transparent pressure-sensitive adhesive applied to at least a portion thereof.
