It’s kind of hard to tell for this image, I think the background is probably real, or at least, created separately. but there are a couple sus features in the foreground. Superman’s right hand, the green jacket, and the apparent facial features of children I mentioned before.
It does have a signature in the bottom right, so I guess you could track down the artist to find out for sure, but with my first comment, I was just pointing out the comedy of kids with facial hair.
Unless the lorry was driving over the exact geographic north or south pole.
Side note: the tallest lorry where the top doesn’t move faster than the speed of light at the equator is 3.8 light hours tall, which is weird to think about because the top doesn’t start moving until well after the bottom has reached it’s destination.
