Card from London

Several days ago I've got a card from Mary, who is also interested in Postcrossing. She's sent me a nice cards with London places of interest.

She's written on the card “Big Ben is the nickname for the great bell of the clock at the north end of the Palace of Westminster in London, and often extended to refer to the Clock and the Clock Tower. The Clock has become a symbol of the United Kingdom, particularly in visual media. When television or a film-maker wish to indicate a generic location in the country a popular way to do it is to show an image of the Tower,  often with a red double-decker bus or a black cab in the fore ground”
It's a pleasure to get unusual card with interesting information.

Thank you, Mary!
