This poster from Yugoslavia is fascinating. That’s not Roy Scheider (dig the shorts) and those are the wrong guerrilas. And, of course, nothing blows up behind the truck. But the thing that really struck me is that someone found it necessary to put a license plate on the front of the truck.
Remember, this was 1978 (the Yugoslav release), so all this was done pre-Photoshop. Sorry for the sub-standard image quality.
