What are those flags hanging above them? The one on the right looks like the flag of Lithuania Minor (aka Prussian Lithuania) (see http://en.wikipedia.org/wiki/Flag_of_Lithuania#History ) but I have no idea what the one on the left is.
All I can tell you is that it is a Magen David with a word in the middle that looks like the Shem Havayah, but surely cannot be. Perhaps this was the flag of the Lithuanian Jewish community?
