I realise, of course, that an animal I might consider exotic could be entirely commonplace for other people. It depends on your point of view. I have split the cards into my own personal view :)
My particular favourite of the endearing crowd is the one on the top left above. The caption on the back reads "Which is the odd one out?"
It's not to say that exotic animals can't be endearing too. I love the snow monkeys from Japan, sitting in a thermal spring while the snow falls on their heads.
Top left and bottom right in this set are maxi-cards from Australia, with a corresponding stamp on the front of the card.
