I have posted a red English phone booth, and a red double decker bus. These things are often seen in London. But if I had to post one red photo that always makes me want to start looking for airfares to London Heathrow Airport, it would be a picture of London's Underground sign, especially that of the King's Cross St. Pancras station.
Happy Travels!
