Unusual vintage anatomical plaster model of a chicken. Believed to be made by SOMSO of Germany, on one side is the plumage and the other shows the internal organs. The model is solid (no removable parts, and no breaks). The base is missing a label which most probably would have detailed all the organs that are numbered on the model. There are some minor chips to the plaster, which is to be expected for something dating from the 1930s. A great and very rare decorative piece.
