First up we have an illustration comparing orc sculpts from various old miniatures lines, from the Dragon article "Will the Real Orc Please Step Forward?" (issue 25, 1979).
I love the orc in the back with the beak-like mouth. And the one in the front with the big smile is awesome. You know that little dude is thinking up some mischief.
Next up is an illo from George R. Paczolt's Rat On A Stick, published by Judges Guild in 1982. I love this module because one of the plotlines you can follow (or not) is opening up and operating your own dungeon-based Rat On A Stick franchise.
