Those don't look to me like original the Motown pressings I saw in The Motown Vaults in 1978. One was a cream-coloured uncredited (no artist name) Jobete Music acetate (used only for song proof of ownership, and another was a 10-inch Motown Originals acetate with, if I remember correctly, 5 or 6 of their songs, from 1965. These 2 look too new (from the 1990s - probably made after the originals were auctioned of at the beginning of the 1990s). Even in the mid 1970s, when I first saw the real acetates, the paper on them from being pasted on only 10 to 13 years before, was already yellowing or browning slightly from oxidation. Also, I've never seen that particular print font on a 1960s Moton or Jobete acetate or vinyl demo record. Clearly, those paste-ons were done after 1990.
