From past experiences with the 1987 TCMA reprints. The BLUE print back would be original, and the BLACK print backs would be the reprint, but retain the same copyright date as the original print. And depending on when the reprints were done in 1987 they may come without the MLB logo (early reprints) or with the MLB logo (later reprints), and in some cases both variations may be available.
