This is the paper and resin version of the coral stone inlay Sant’Agostino (Rome) floor plan pendant — part of my architectural floor plan series of fortresses, castles, villas, & churches in Italy. The frame was hand-sawed from 1mm sterling silver sheet to the scale of the diagram found in a vintage Italian travel guide. The silver has been antiqued with liver of sulfur, and resin protects the paper.
The frame is soldered onto a back sheet of silver. Before the paper is meticulously cut and placed into the frame, the pendant looks like this below (oxidized version and silver version). It measures 38x54mm.
