Pingu at the Circus helped give an idea as to convey a Circus primarily for pre-school television.
Chuck Jones also began producing the Loony Tunes cartoons, along with Tom and Jerry & Woody Woodpecker. I began watching these to see how the 1950's style became apparent in the backgrounds and characters.
I began looking into 1950's textiles, some of the bigger designers such as Stig Lindberg, Marian Mahler, Mary White and Lucienne Day.
My Grandparents also sent me some photos and clothes from the 1950's for me to use. These have become incredibly useful as I want to achieve not only the textile styles but the fashion of the Fifties too.
(I've had to blur the faces for privacy reasons)
From there I began brief designs of my clown character who I've named Tilly.
