A group of seven 1950s period Christmas cards sent by Joan and Sir Basil Spence (the important British architect).  Four have moveable features - eg the door opens or Basil and his cat become visible inside windows, etc.  One of Basil as a dog seems to be all done in pen and ink (two colours) - this was probably done by Basil rather than Joan.  Some of the other cards may well have been written by Joan.
