Back in the 80's I went to a Halloween party and somebody was dressed as "the Bill". It looked pretty good. IIRC, it was mostly a roll of foam rubber with a hole cut out for the face and arms.
To graduate Architecture school where I went you had to have a minor in art... a few in the school did this sort of stuff and I never understood it. To me, art is an expression of talent fused with something emotional to catch a moment in time or covey a feeling. This stuff is juvenile rebellion for the talentless. It has no meaning.
As for Hunter's art... it will go up in value in 10-20 years is my guess. The odd genesis of it's creation will drive it along with the history that's going to be written in the next 3.5 years on why it was done and the uniqueness of a stolen elections.
