Imagine you are a non-English speaking Arabic tourist, visiting London for the first time. Before you leave, to return to your native Saudi Arabia, you visit Camden Market and buy a souvenir in the form of a poster saying 'KEEP CALM AND CARRY ON'; although you, yourself, have no idea what it says.
You return home, find a suitable frame for your souvenir, then hang it upside down.
Well, that is a bit how I feel about the above. I bought it many moons ago and it has been hanging-up ever since, but I've never known which way up it should hang. I imagine that the 'squiggles' in the middle do actually say something; possibly of religious significance.
I have no idea of its origin, but imagine it is either Indian or Arabic. So, if you are an Indian or Arab scholar, and have the answer, I'd love to hear it. If you have no idea at all, yet have a humorous suggestion, I'd also like to hear that too.
Answers on a postcard please....
