Tabby and Calico are not breeds, they are coat patterns.
Definitely looks like a main coon in the face. Nothing to compare to in the picture, but if he's an adult, full grown main coon, you won't be able to mistake it. They get huge. My cousin has a main coon. They are freaking huge. This one is not hers, but it should give you an idea of how big they get. The good news is, even though they are big, my cousins (and most from what I've heard) are incredibly laid back. That's good, cause this thing could kill even a medium sized dog if it had a mind to!
EDIT - To give you an idea of just how intimidating a Main Coon is - even though my cousin's cat is incredibly laid back and never done more that give it one good swat when he got too close too quickly (the cat will let him smell and lick him so long as he comes up slowly), my cousin's roommate has dog that is 50 lbs and the cat bosses it around without even having to hiss. The dog just goes, "I think my life will be better if I never once have to see this thing mad."
EDIT EDIT - My cousin's cat is slightly overweight at 25 lbs =) that should give you another idea. When I say "slightly" I mean you wouldn't even say "pudgy" just looking at him, but when you pet him you realize his body fat is high enough it has lowered the definition you feel in his features.
EDIT EDIT - It's also possible your cat has main coon in him, but is not full blooded (that would explain the face even if he is not big enough).
