Series 1, #5b. 1985.
Another from the inaugural Series #1. See also Adam Bomb.
When I was in 4th or 5th grade one of my friends had found a store that had a ton of packs of Series 1 left on clearance. At the time, Series 2 was out and Series 1 was hard to find. He sold me a bunch of packs and this one and Adam Bomb are the only ones to survive.
