On the left side of the escalator, there is a sign with a red circle and a white line through it that reads "No dogs allowed". Below the red circle, there are two smaller signs with a black and white image of a dog and a person in a stroller. The signs are also red and white and are placed on a white surface. The background of the image shows the interior of the subway station with other escalators and lights.
