The monument commemorating the victims of the Częstochowa ghetto in Poland was vandalized with swastikas and other Nazi symbols, including a favorite of white supremacists - the number 1488.
Neo-Nazis use the number 88 as a code to represent the slogan "Heil" Hitler. The number 88 is often used in combination with the number 14 (e.g. 1488 or 14/88). In this context, the number fourteen stands for Fourteen Words, which is a famous neo-Nazi slogan created by sentenced terrorist David Lane ("We must secure the existence of our people and a future for white children").
The names of Jurgen Graf and Ursula Haverbeck, notorious Holocaust deniers, are also inscribed on the monument.
