Hand-painted Australiana table lamp with revolving celluloid shade

• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
• Celluloid - In 1864 an American scientist by the name of Parkes mixed camphor with nitrocellulose, etc. The result was what came to be known as "celluloid", the first form of plastic, and a product for which Parkes could find no use.
  
  Some time later when the supplies of ivory for making billiard balls were becoming difficult to obtain, an inventor produced a perfect billiard ball from a mould using "celluloid".
  
  Toys, dolls and other products such as combs, cutlery handles and costume jewellery made from celluloid began appearing on the market from 1913 and continued to do so until the early 1950s by which time it was superseded by more modern products due to safety concerns because it was highly flammable and brittle product.
