collecting postcards

We received these postcards from my father in London this week.  It reminded me of the postcard collection I had when I was younger.  My father started that collection, as he used to send my sister and I a postcard whenever he went overseas. 
Postcards make a great item for children to collect.  There are many ways in which they can be used for learning.  Each one gives a little bit of information about the place they were sent from.  You could also collect postcards of particular things, for example, animals or works of art.  Once you have a bit of a collection the postcards can then be used for talking about characteristics and making comparisons of different places, animals, works of art and so on.
To kickstart our collection I will ask various family and friends to help us with a little mail swap, since they are scattered around Australia and the world (and since B is very interested in sending and receiving mail lately).  Another way you can get a collection started is by joining Postcrossing.  I’m happy to swap with any of you as well – leave a comment if you are interested.
