1987 Donruss was by design.
There have been random 'flipped-back' cards seen in various products throughout the years. Those are not by design, and are printing glitches, which are not logged here (see the FAQ).
If this is the case that Topps intentionallty did that to be able to tell the difference bewteen the packed-out cards and the factory set cards, then we could add them. However, since we don't know, we won't be adding them. If you want, submit the info to the Trivia section.

Note: Please see my profile for more info regarding trading (section updated 10/25/2023). I have added a large portion of my inventory to the site, and currently have trading turned off (details are in my profile). I have (finally) unearthed my 2 very large boxes of Star Company minor league sets and they are available (email for details).
