I've recently seen, on a couple of cars around the Bay Area, a sticker featuring three squares in a row.
One square is red.
One is green.
The middle one is white, with a menorah on it.
Mexican Hanukkah? Italian Hanukkah?
I find the question asked on the Web, but not answered: what is it?
Or is the emblem in the middle not meant to be a menorah at all, but something else entirely? The White Tree of Númenor, perhaps?
