I'm with Storch on this one.
The Pig is focused in crystal clear but the man behind it is not (not talking about the face which might have been blurred deliberately). I'm going to take a stab at this (wild guess), I'll bet a P&S type camera was used. They just don't have the tight depth of field a fast lens on a 35mm film or DSLR camera has. The man and the Pig aren't in the same depth of field. I'm only going by the photo details but looking closely, it appears the man's hand isn't actually touching the pig as it appears to be a posed photo. The man is probably closer to 10 feet behind the pig.
The article claims the pig to be 12 feet long, no way. I'd say closer to 4-6 feet in length.
