Rocky has just been out for his one piece of exercise a day, following the advice of the government, and posted a birthday card to Karen's great nephew.  Royal Mail staff will empty this postbox today and send the card on its way.  Rocky wants to know what colour the post boxes are in your country?  Can you post a photo so that Rocky can see?  What do the stamps look like?  In the UK, stamps usually have the Queen's silhouette on, but may have other images at special times of the year.  What about the stamps in your country?  Can you design a stamp that links to our project?
