MARSHAK S.YA. (1887-1964) Sinie zagadki - krasnye razgadki [Blue Riddles - Red Answers]. Leningrad: State Publishing House, 1928.

[12] pp.: ill.; 9.5 x 14.5 cm. Illustrated by E. Dorfman and B. Tatarinov. In the publisher’s illustrated wrapper. In good condition. Minor rubbing and tears, soiling in the text block, rust from the staples. A toy book with two-colour illustrations: on each spread a red drawing is printed over a blue one. To see both the riddle and its answer, the book came with sheets of transparent coloured paper (not preserved). The illustrations were created jointly by Elizaveta Grigorievna Dorfman (1899-1942) and Boris Fyodorovich Tatarinov, who together produced several similar books: ‘Where Is the Cat?’ (1929), ‘Blue Riddles - Red Answers’ (1929) and ‘What Is It?’ (1929). E.G. Dorfman studied at the Academy of Arts under K.S. Petrov-Vodkin and worked in book graphics, creating illustrations and posters in the Suprematist and Cubist styles. She died during the Siege of Leningrad.
