Chad Gadjo.

A colourful art book, illustrating the famous Passover hymn Had Gadjo (Chad Gadya in English spelling).

Menachem (1893–1944) and Uriel Birnbaum (1894–1956) were sons of Austrian-Jewish Philosopher and journalist Nathan Birnbaum (1864-1937).
Menachem was an illustrator and portrait painter who lived in Berlin from 1911 until 1914 and again from 1919 until 1933. He then emigrated to the Netherlands. In the spring of 1943 he was arrested by the Gestapo and with his relatives and transported to a Nazi concentration camp - presumably Auschwitz, where he died. Uriel, artist and poet, who had also illustrated a number of books during his lifetime, survived the war in the Netherlands.
