From a Pink Floyd album cover
This coal-fired power plant built between the two world wars,¡ has become one of the most famous images of London,¡ thanks to its appearance on the cover of Pink Floyd's album "Animals". The famous pig which appears on the cover, floating above the power plant, was a thirteen-meter balloon inflated with helium. While photos were being taken, the pig escaped at one point and reached airplane-height, forcing nearby Heathrow Airport to delay several flights.
