body shape and pose
Hard Plastic Body - Regular pose
The first hard plastic (Styrene) doll bodies produced by Nisbet were the "Historical" range. This body shape was made to stand up on its own, and had the straight legged, facing forward, arms at the sides pose that Nisbet collectors will immediately recognise.
This body shape was also used by the "National Costume" range, and, (with different faces), the "Portrait" range.
Hard Plastic Body - Animated pose
The Belly Dancer above shows the move to a more naturalistic and animated pose. This body shape was used to great effect for a limited range of dolls, namely the Can-Can dancers, and, (of course), the Belly dancer shown here. These dolls were part of the "National Costume" range, but this body shape was also used for a very few of the "Portrait" dolls, including P/643 - Margaret of Anjou, and P/647 - Anne Neville
The "Happy Doll" range were intended to represent children in adult occupations, and so were only 7 inches tall, compared to the 8inch adult doll bodies shown above. They also had a more animated pose, and were able to stand unaided, despite the toe pointing ballet pose. The arms were crooked, which meant that the dolls, (meant to be dancers), could be posed with their arms above their heads.
