Abstract
Various two-part articles, such as metal trading cards, which safely and advantageously combine a metal substrate having front and rear sides, and an insert sheet made of metal, glass or plastic. In some embodiments, both the metal substrate and a metal insert sheet are embossed. The metal substrate includes a central main portion, four edge marginal portions terminating in respective substrate edges, and four corner marginal portions. The marginal portions surround the central main portion, sharing respective boundaries therewith, and are rolled towards the substrate rear side and around such that the substrate edges contact the insert sheet so as to hold the insert sheet in position. The rolled marginal portions together define a continuous bead around the periphery of the card without any exposed sharp edges. In some embodiments the rolled edges are replaced by hinge sleeves. Thus, specific embodiments include a greeting card having two elements joined by a hinge, and a gift greeting box with an insert sheet in the cover, with a hinge joining the cover to a receptacle base.
