Unique and collectable these wall plaques were designed by Arthur Osborne and made of genuine Ivorex in Faversham in the early 1900's. They each carry the Osborne ink stamp on the reverse and on the front corner have the engraved AO initials which were used until Arthur Osborne's death in 1943.

These rare and detailed plaques were first sculpted in clay by Osborne, then unique gelatin molds were made from the clay "master" plaques. A special fine, high-grade, plaster of paris powder was sifted thoroughly to remove any lumps, then mixed with water and poured into the gelatin molds, with any bubbles skimmed from the top. When the plaques were hard they were removed from the molds and air dried in a heated room. After the plaques were completely dry the color accents were hand painted on using watercolor paints. When the paint was dry the plaques were dipped in hot paraffin wax, which gave the plaques their "ivory like" appearance, and then buffed to a beautiful shine.
