Royal Doulton Daydreams HN1731 was a very popular piece as it was made from 1935 to 1996. As with many pieces Doulton manufactured they would create them in different colours to see if they would sell better at the time.
With HN1944 you would have thought it would have sold well given the fact most of the very popular pieces were made in red as well. But she was only in production for 9 years 1940 to 1949.
She is 5.5in tall.
