You may well be familiar with The War that Time Forgot, a recently-reprinted beast from the 1960s in which WW2 GI's find themselves on a pacific island populated by murderous dinosaurs. You might be less familiar with this series of covers by Pete Von Sholly, which I am sad to say are a parody of The War that Time Forgot and not actually a real comic. I don't know why anyone would seek to "spoof" a comic that I can open up to any random page and find a man skiing across a chasm while shooting a vicious, flesh-craving Iguanodon in the mouth, but there you go.
