A group picture

A group of German tourists wanted that I take few
pictures with their small cameras in front of the Hertford house,
where is the Wallace collection.
 And so I asked if I can make a photo of them to Blipfoto.
I could only take five shots.  In two first they smiled so much that
I had to ask them to be more as they are withous smiling.
I don't know was it too much to be asked, but I like this photo a lot
more than the first smiling ones.
