The image is a close-up of a sign on the side of an airplane. The sign is rectangular in shape and has a white background with black text. On the left side of the sign, there is an arrow pointing upwards with the word "WC" written above it. Below the arrow, there are three icons - a man, a woman, a phone, and a person walking up a flight of stairs. 

On the right side, on the bottom right corner, there appears to be a phone number and a credit card. The text on the sign reads "ALERTE SNCF TEL 3117" which translates to "Emergency call" in English.

The sign also has a green heart symbol on the top left corner, indicating that it is an emergency call.
