The dome of St Paul's Cathedral is a familiar sight in the London sky line. Colour in this fantastic illustration (which also has a great double decker bus) and then write a message to someone on the back!
Colour in the picture of the Tower of London on this postcard and then make a trip to the post box to send it! Its easy to make; just print it out and stick the two sides together.
Tower Bridge is a famous London landmark and the fantastic illustration on this postcard shows it rising up to let a boat through. Postcards don't need too much writing so are good way to get reluctant writers going!
The London Eye is a relative newcomer to London. It was built flat, over the river, before being hoisted into place for the millenium celebrations. This postcard shows one of the pods in which visitors make their journey around the giant wheel.
