Chalkware has been around for centuries in one form or another. The chalk ware figures were made of sculpted gypsum or cast from plaster molds. The figures were painted by artists of different levels of expertise. Therefore finished figurines, cast from the same mold, have their own distinct quality and personality depending on the talent of the artist and the age of the mold used.
During the Victorian era in the US, decorative figures were often peddled on the street or door to door by "Image Peddlers." Later, beginning in the Depression Era, Chalkware figures were often used as Carnival Prizes. Molds for Carnival Chalkware were typically used over and over to create a large amount of figures as cheaply as they could. The Carnival Chalkware was often garishly painted (with water colors)and usually offered less distinct detail than some of the earlier pieces.
Even though this Scotty has considerable detail, I believe he is likely part of the 30's Carnival Chalkware. If he was ever painted, the paint has totally worn away but my guess is that he never bore the burden of the very often ugly painting found on many of these pieces. The dog is quite uniformly the color of sand. The detail of his wiry hair offers texture. I find no damage of concern...a few nicks at the base. His tail is short and smooth but I believe it has been that way since his creation. He measures approximately 6 1/2" long (6" at the base) and 5" tall. The base is 2 3/4" wide.
The letter A was carved into the bottom of the base probably by the person who formed the cast.
