Seems plausible to me.
In the late 70's there was a "craft" that involved making transparencies from printed matter. A bit of scotch tape or better yet packing tape, a bowl of water and a bit of rubbing to remove the paper and the transparency was done and ready to frame as a suncatcher. I did a couple 79 Topps commons and it was pretty easy.
Substitute some better plastic film, and an adhesive that can be easily removed from the ink after it's been readhered to a new card and it's pretty likely the process.
Prepping the card to provide a new back looks a bit tougher. The scraped surface would be obvious because it's not smooth. But I'm betting some simple chemicals would do the trick, leaving the smooth white cardboard surface.
