The State Capitol, Jefferson City, USA was started in 1915 and
completed in 1925. The scheme consisted of four pendentives each 731.5
cm high (24 ft), 146.3 cm (48ft) wide at the top and 457 cm (15ft) wide
at the base; additionally there were 8 lower dome panels approximately
487 x 853 cm (16 x 28 ft).
Dean Cornwell, one of the most successful American illustrators of
the first half of the Twentieth Century worked as Brangwyn’s assistant
from 1926-1930. Dr Libby Horner has suggested that Cornwell – who
frequently outlined his own designs in blue – produced this sketch of
the recently finished State Capitol murals to demonstrate his
skill
to Brangwyn whom he hoped would employ him as a studio assistant. His
desire to work as Brangywn’s assistant at this point
was to benefit from Brangwyn’s experience as one of the most successful
living muralists: Cornwell was shortly to start work on his own project,
a commission for the Rotonda of the Los Angeles Public Library,
1927-32.
