Zoom in and look at the persons below the billboard. Below the statement, read the text on the billboard that shows what brand the billboard it is.

There are other issues too if you look closely. The reflection in the building windows of a non-existent car, the strange merging of two separate buildings in top left corner, the malformed black car on the right side of the image, the street that merges into a building, the malformed traffic light on the left, the black car with human persons protruding through the bonnet like video game characters clipping into other objects, etc.

Edit: added some other examples
