Good Ideas Super Star Action Pop-Ups (1988-1989)

     I caught this a month or so ago in the course of my usual daily eBay Winfield hunt. Having no idea what it was or from whence it came, upon its arrival in the daily post, I plunged deep into the murky depths of the web seeking enlightenment. As happens more often than not, ManOfSteal over at Rickey Henderson Collectibles had the scoop. He'd picked up his 1988 Rickey Pop-Up years before. A few questions back and forth over on the Freedom Card Board Rickey Henderson Collectors Thread didn't reveal too much more aside from the fact that there are 1988 & 1989 series.
