Technical Observations: 1952.41 has been stripped of corrosion products, and the surface is now slightly oxidized bright metal and very pitted, with black material in the pitted areas. The right rear leg is broken and dislocated at the knee. The other stamps (1920.44.224, 1966.108, and 1987.33) are mostly green with areas of red. 1966.108 is mostly mineralized and the surface has been cleaned, leaving scrape marks in many areas. The tail is lost. 1920.44.224 has most of its rough corrosion products intact. The tip of the beak is lost. 1987.33 is broken and crudely repaired at the post under the left bird and the strut between their necks. Portions of both birds’ tails are lost.
All of the stamps appear to have been modeled directly in wax prior to casting. No evidence of metal joins is visible. The large horse’s (1952.41) base appears to have been constructed from strips of wax rather than pierced from a wax sheet. The strut between the bird pair (1987.33) projects through the neck on the right bird and was probably set into holes in the necks in the wax model.
