These pictures are taken from the 'My Little Pets Picture Book', from the 1940's. Illustrated by Ruth E. Newton I'm not sure who the author is, I do know however that the images are beyond charming. Ruth E Newton, was born in Pennsylvania in 18894. Ruth retired in 1968 after a career illustrating books, designing dolls and producing greetings cards and advertisements. She passed away in 1972.
I haven't been able to find any more about the book itself out, so enjoy baking in the glorious colours for now...
