Wine or Beer Barrel

At first sight it looked to me like King David and his shield. Then I saw that the “shield” is a wine or beer barrel and the whole meaning changed. Then I read the words and understood that it is an old postcard of Hensel Berlin restaurant. Then I thought if it appears on Stephanie Comfort's Flickr pages it probably had been a Jewish restaurant, since she’s collecting Jewish pictorial history. Picture is courtesy of Stephanie Comfort
