I was recently reading up on Wikipedia regarding the Tomb of the Patriarchs, and was particularly interested in this picture: https://upload.wikimedia.org/wikipedia/commons/8/89/Cenotaph_of_Abraham_-_northwestern_view.JPG
I'd like to learn about the signs with Hebrew writing (on what seems to be black velvet?) and the history behind them. Would it be appropriate to ask such a question on the main site?
