Much of the research on the 3d Beaded Oval was undertaken by Mr Purves, although no plating details have previously been published.
This volume commences with a comprehensive account of Robinson’s plate-making technique for surface-printing from electrotypes. It is followed by a detailed description of the types and causes of the many varieties to be found. This is perhaps the first time this information has been given in such a comprehensive yet self-contained manner. lt will bestow knowledge on many and refresh that of the advanced reader. All the various printings are covered with additional information from archival records.
The final chapter deals with the Plating Study. Each position is illustrated by a 150% enlargement and is accompanied by a detailed description. The plating nomenclature follows that developed by Mr Purves.
