The second translation maybe "Comfortable Zhendong Chinese Typewriter" as in the town of Zhendong (振东) in the Binhai county located in the Jiangsu province.

Zhendong happens to be directly north of Shanghai, where the pioneering Wan brothers were doing animation experiments at the time.

The black and white advertisement was created for the Shanghai Commercial Press (商务印书馆).
