I think that for a certain subset of this blog’s readers, photo challenges are enjoyable.  I’ll tell you a little and you can tell me the rest.  This photo is part of the Jerusalem volume of The American Colony and Eric Matson Collection and it was taken in approximately 1900.

The best answer in the comments below wins a free copy of the Jerusalem CD (or your choice of another if you already have it).  An important part of the answer is why it is impossible to take this same photo today.
