Take your 6.8 out and bag one of these. >
It's big, but you are right. They used forced perspective to make it look like the hog was bigger. The kid is actually standing several feet back from the hog, thus making him look smaller. Still 1000 pound hog is nothing to sneeze at.It was actually a farm-raised pig... and there is some slight trick photography going on. It wasn't QUITE that big.
But still about 1000 lbs.
