Kalender fur das Schaltjahr 1928. [no publisher, no place, 1927].

Title page and 24 interleaved pages, followed by four pages of Protestant, Catholic, and Jewish Festivals all in red and black print.  No inscriptions. Original cream endpapers. 31 x 44 mm. Original full straight-grained black morocco binding.  Five years later, in 1933 (The "Coordination" / Gleichschaltung), following the Nazi rise to power, secular and state-run publishers immediately began to remove references to Jewish holidays in mainstream almanacs. This aligned with the nationwide boycotts of Jewish businesses on April 1, 1933, and the Aryan Paragraph (which restricted Jews from public institutions) the same month. In the following three years, Jewish festivals were almost entirely absent from general public and state-produced almanacs. During these years, Jewish festivals were generally printed only in explicitly Jewish publications (such as the Jüdischer Jugendkalender or those produced by the Reich Representation of Jews in Germany).  In 1938 (Complete State Censorship), the complete eradication of Jewish timekeeping from the public sphere was finalised in 1938, when the Nazi regime implemented strict regulations dictating the content of all almanacs, enforcing the inclusion of new Nazi holidays (like Hitler's birthday on April 20) and banning the printing of Jewish religious dates in non-Jewish calendars.
