It’s a battle of dinosaurs

If the criteria is wacko art, then I think the crappiest look should win. Those metal dinosaurs are really well-executed, and the paper mache stuff looks like hell. 
Therefore, I suggest that the paper mache art wins.

If your looking for "wacko" I'd choose Little Johnny.  I think the other dino is just "artsy".

The metal dinosaurs look too arty, so I'd have to go with the giant dinosaur attack with alien bonus yard.

Papier Mache always wins over fine welding art.

Paul, I'll give you two dollars if you pick the metal dinosaurs.

I know I'm too late, but could Christmas lights/decorations that are still up be considered whacko? 

I vote Papier Mache dinosaurs...very cool,er...weird, er...whacko.

Papier mache dinosaur is more "wacko" and less "art."

Metal dinosaurs are less "wacko" and more "art."

Depends on your emphasis.

Since the operative adjective is "wacko" describing the noun, "art," I'd have to throw my lot in with the papier mache dinosaur.

OK, I'm going with Mary as the winner. Congratulations, Mary!

A more formal announcement of Mary's victory will be posted soon, pending my issues with creating the artwork for said post.

Those rules are there for a reason, mister.

"Arbitrariness" isn't a reason.

Yay!  Thank you!  I'm glad I had my camera with me that day--I should carry it more often.   There's a lot of weird crap around here.

And Mark, thanks for posting the pictures of the classy dinosaurs--I never would've known they were there otherwise.

You're welcome Mary. Congrats!

Fixed!
