Two sides of war

 British troops setting off for the continent.

Prisonners of war.  I imagine that many families would have been pleased to receive this card.  On the back the details of their soldier and the address of the camp he was being held in.

Tom Tits and Chaffinches

I found each of these cards separately and by coincidence when I was looking for something else. They were published by Raphael Tuck and Sons. There are lots more of their cards for you to browse through here
