Mogador

Photo is courtesy of "time fly". He published it on Flickr with the caption:
There has been a Jewish settlement in Essaouira since before the Phonecians. The quarter ...is still in good shape, but homes and buildings are identified by a 6-pointed star.

"time fly" wrote to me that this photo was taken in the Moroccan seaside little town of Essaouia. The Jewish community there dates from around 1700.

Snow Flake

Winter Meet Autumn, Autumn Meet Winter
and wrote in the comments section:

I use a 50mm 1.8 II fitted with a +10 B+W macro lens and of course a tripod. Oh... and I am lucky ;-)

Let My People Go

Let my People Go Stamp
A Blue Star of David on a closed door and under it the proclamation: Let My People Go in Russian, Arabic English and Hebrew
Day of issue: 07/03/1972
Designer: Israeli artist Moshe Pereg
It seems fit to quote here the famous African-American spiritual song

When Israel was in Egypt land,
Let my people go.
Oppressed so hard they could not stand
Let my people go.
Oh go down, Moses,
Way down into Egypt's land,
Tell old Pharao,
Let my people go.

First Zionist Congress Souvenir Sheet

There’s a Star of David (and an icon of Herzl and an Israeli flag) on the Souvenir Sheet issued on 03/09/1996.

the First Zionist Congress was held in the Casino building in Basel, which is shown in the center of the sheet. 

Composition

Photo of a black Star of David window on azure wall is courtesy of "César Augusto" who published it on Flickr. It was taken in Algarve, south of Portugal, from the façade of a lone house where nobody lives now, where César Augusto used to spend his holidays every year. I like the composition, and the uniqueness of the making of the symbol from stones cut in order to fit its contour.

Jewish Bookplates

Photo of Stars of David on the Eichthal Coat of Arms is copied from Jewish Encyclopedia

I feel that Jewish Bookplates are a promising source for Star of David searchers like me. E.g.:
The Bookplate Collection at The Jewish Theological Seminary Library which has about 3000 items.
