The picture shows Jonas and the Giver. You can see the face of the Giver with many wrinkles and a long, white beard but just the back of Jonas. The Receiver puts his hand on Jonas shoulder. We think he transmitted him the memories of the "world". The Giver looks weak and tired. Maybe its really exhausting for him to transmitted him the memories. You can't see Jonas face so you can't conclude of his facial expression and how he feels in this strange situation.  It seems a bit mysterious and secretive.
