knock knock

I went to Morocco last Thanksgiving and stayed at the lovely little Riad Kaiss in the medina in Marrakesh. One night I got lost wandering through the alleyways. I was a little scared, but I had to stop and shoot a picture of this Hand of Fatima door knocker. I find it so clever and creepy, but it's said to bring good luck. When I saw the photo I was sorry that I didn't buy one there, but they do sell them online at Berber Imports.

Should I put one of these on the door of my apartment? Or would it ruin the look of the Deco building?
