Ching Ling and Ting Ling
Elizabeth McCrady
Paperback
(Platt & Munk, March 15, 1960)
Platt & Munk originally published this series of children in different countries in 1936, as paperbacks. They were only reprinted once, in 1960. Same paper, brilliant illustrations. The format is a kind of day in the life (in the 1930s!) for these children. Great collectibles.
