Time to Eat Go! Go! Go!!

A poster in Times Square exhorting us to go! go! go! get some GI rations upstairs pronto. Just fall in with the cutlery-wielding Marines as they charge hellbent over pumpkin-laced minefields (or provide suppression fire from behind giant mutant cabbages). And all with air cover provided by fearsome pickled corn cobs(?). I honestly don't know which WWII movie this is trying to reference, but it apparently won all kinds of awards at Cannes - just look at all those wreathes!
