This is a nineteenth-century European postcard featuring a photograph of a boy eating matzah and standing next to two sacks of matzot. The title is  Ma Nishtana Halayla Hazeh  (How is this night different from other nights?), one of the four questions from the Haggadah which is usually recited by children. The Four Questions raise the unique features of Pesach which include eating matzah.

The postcard was part of a set of postcards published at the end of the nineteenth century, illustrating the Jewish festivals in Western Europe. These postcards were used as greeting cards for the New Year.
