Okay kiddo, have you ever heard of letters and how we use them to communicate with people who are far away? When we send a letter, we need to put something on it called a postage stamp. This is like a sticker that shows that we have paid for the letter to be delivered to its destination.
Now, way back in the olden times (like more than 100 years ago), people in a place called New South Wales in Australia also had to use postage stamps. These stamps had special designs on them that showed different people, things and places related to New South Wales. People in New South Wales used these stamps to send letters to other places in Australia and even to other countries!
These postage stamps weren't just about paying for the letter to be delivered, they were also like tiny works of art with different designs and colors. Some of these postage stamps were very rare and valuable, which means they were worth a lot of money to collectors who like to collect rare stamps.
The postal history of New South Wales is all about how people in that place used to send letters and packages to each other and to other parts of the world. It's really interesting because it shows how important communication was even before we had things like the internet and smartphones.
So, remember kiddo, postage stamps are like stickers we put on letters to show we paid for them to be delivered, and in New South Wales, they had really cool stamps with designs related to their place!
