The image shows a double-decker bus on display at an exhibition. The bus is blue and white in color and has the words "BIO GAS BUS" written on the side in bold letters. The words "The world's first double decker bus" are written in smaller letters below the main text. 

The bus is parked inside a large building with a high ceiling and large windows. There are several people standing around the bus, admiring it. On the right side of the image, there is a sign that reads "Take Control" and on the left side, there are several other buses visible in the background.

There is also a blue carpet on the floor and a white pillar in front of the bus. The overall atmosphere of the exhibition is modern and professional.
