A Weidlich Tapestry bread tray was one of the first pieces of silver I bought as a teenager, still like the look of it. Have always known it as an acid-etched design, but a few idle moments to do some research turned up the patent for the technique (#1,717,482, filed in 1923, issued in 1929). In short, the design was acid-etched into a metal plate, the transfer was produced from that metal plate and repeated several times onto a larger master plate and acid-etched, that master die was used to produce sheets of rolled stock, which was used in regular shaping dies to produce the holloware. The acid etching was quicker than die-cutting, and using the rolled stock sheets in the plain shaping dies was less expensive than having to produce shaping dies with sunk decoration.
