Appraised at $4,500. Audubon's warblers with palo verdi (introduced 1964 500 pairs made). They are 4" x 8.5" Stand is 1 " high. 

The porcelain birds in these cases were sculpted by Dorothy Doughty, artist and amateur ornithologist, at the request of the Royal Porcelain company of Worcester. 

Miss Doughty's rendering are so lifelike due to her great attention to detail ranging from accurate color reproduction to the process by which the sculptures were cast and fired. 

Dorothy Doughty, born in San Remo, Italy in 1892, painted her first watercolor with her mother's help at age two. Later she studied at the Eastbourne School of Art. The North American Bird series was her first work using porcelain. Early in the project, she decided that working with live birds would render the best results, so she obtained and kept most of the birds in an aviary. Other birds indigenous to North America were studied during her two trips to the United States

Despite their fragility and the technical difficulties of manufacture, they have remained popular to the present day. The North American Bird Series, produced from 1935 through 1968. All figurines are hand-painted and limited editions.
