The Indian faces beads shown are more likely to be from the 1990s and later. Though the late '80s is not impossible. The first Indian mosaic-glass beads I saw, in 1980 in New York City, and later that year in California, that had faces canes were very different. It was some years before beads that featured only face canes, in the conformations we see in this thread, became commonplace.
