"In this Menorah I have three men and three women; three young people and three older people. The luggage in the front shows the major European countries and how many Jews died in each of them. In the back are three columns in the shape of the electrified fence at Auschwitz. The three columns combined form the Hebrew letter “Shin.” It is the letter used on the exterior of a Mezuzah, It is symbolic of one of the names of G_d, and is also a symbol for the priestly blessing."
— NY Jewish artist, Aaron Morgan (more of his Holocaust inspired art here, but this menorah is his magnum opus).
