Amsterdam-based advertising bureau Etcetera has developed a special poster for fast food chain Halal Fried Chicken during Ramadan.

Between dawn and dusk the poster consists of a blank page and the name of the company. But once the sun has gone down, and the period of fasting is over, the poster features a pile of deep-fried chicken and tells viewers 'enjoy your meal'.

The poster was made using special printing techniques and makes use of the lighting in the bus shelter to show off the food. It has been displayed at eight bus and tram stops in Amsterdam and Rotterdam.
