The statue on the left has me really puzzled. The arm is out away from the body. Theres no vertical support for the top half of the body. Is that single point where the suitcase touches the thigh holding up that statue? I’m thinking of the wind outside blowing on a sail. 
The arm is more vertical on the other statue (right side of photo) but still not much support at the thigh.
It’s a cool looking statue. Hows this thing standing?
Interesting sculptures. Your hunch about the support point being the suitcase appears to be right. Look at this image: http://bumbumbum.me/wp-content/uploads/2010/04/brunocatalanos1.jpg
The point where the suitcase touches the leg appears to be a joint of some kind.
ETA: better picture (of a different sculpture) from his website that makes it clear.
I don’t know details about the sculptures, but there’s no reason that the "relatively fragile’-looking bronze connection between the leg and the suitcase couldn’t contain some strengthening element, like a piece of rebar. In fact, I wouldn’t be surprised if some sort of bent “spine” didn’t go all the way from the base (below the base even, maybe extending into the ground) all the way to the top.
On top of which, most statue casting metal is pretty strong by itself.
They’d have to be strong to withstand winds on a seacoast.
I’d love to see one up close. See if that shoulder has any wiggle. 
They are creative works of art.
Another speculation: The insides of those statues (in particular, the inside of the leg and the inside of the suitcase) might be solidly filled with very heavy material (steel? cement?) while the upper part might be especially lightweight material (and the head may be hollow).
Thus, by putting a lot of weight in the lower parts, and very little weight in the upper parts, you get the center of gravity way down low. That would help it to stand up.
Also, the base of the statue, underneath the foot, may be solidly bolted into the ground.
Still, I wonder how much wind force there may be on the sail-like upper parts.
Huh, the suitcase is just attached to the leg. These are 2 pictures of a statue I saw.
