The specimen card titled "Coins Arrondis" displays a collection of elegant rounded corner elements in various designs and weights. The numbered arc elements are systematically arranged and surrounded by a richly decorated frame with floral and ornamental motifs. These precisely engraved printing elements were used to decorate corners of documents, certificates and business papers, giving rectangular printed matter an elegant rounded shape.
