Now for WWI: Jane G C, the human belonging to late and much-loved blog friend Whicky Whuudler, sent along a link full of excellent photos. Some you'll have seen before, but I'll bet you haven't seen Ching of the HMAS Swan shaking hands with a sailor, or Pincher of the HMS Vindex parked on a very early seaplane.
Those and many more are here. Enjoy!
