First edition jacket for The Band of the Red Hand, an early book by Margaret Rau, who was born 1913 in Swatow, Guangdong, China, and later lived in the United States. The “Chinese mystery story” is directed at children and was published by Alfred A. Knopf in 1938, with cover art by Joseph Low.
The title typography combines Signal with the shaded caps of Plastica, another 1930s Berthold release. It could also be Ludlow’s Umbra, which is virtually identical for the letters in question.
