It is easy to see from this picture where all of that sausage will go. I do believe the boy killed a relative.
Comparing the two photos the first one appears the boy is kneeling and a little further away from the boar thus making the boar seem larger. When you compare it to the photo with son and dad they appear to be much closer to the boar thus making the boar not so outlandishly huge.
Wow! He is enornmous, and the hog is big too!
You use the old "hold the fish straight out and closer to the camera" trick to make it look bigger. In this case, the hog not being movable, the kid posed farther away from the hog to make it look much bigger than it actually is in relation to him.
Which one’s the hog?
