On the subject of non-controversial posters seen around Damascus, I bring you...well, YOU.
I saw this on a side-street near Sahet Arnus. It makes (slightly) more sense when you can see the shop itself. Apparently, this business will put a picture of you (who else?) inside of a crystal block.
From the 5-o'clock shadow to the delicate placement of the model's (or, more likely, the shopowner's brother-in-law or something's) hands, there is nothing not to love about this bizarre advertisement.
