I just noticed that my copy of the Complete Motown Singles Volume 6 does not have the extra sheet rubber cemented onto the back. All of the other sets in the series that I have in my collection have this extra sheet on the back. My copy of Volume 6 was purchased new about 2009 or so, but it was one of those that miraculously showed up after the set had been unavailable for a while.

Did the earlier copies of Complete Motown Singles Volume 6 have the extra sheet stuck to the back? I checked with my daughter, who also has a copy of Volume 6, and hers does not have the extra sheet either. However, her copy was purchased about the same time as mine and from the same source, the Tower Records website.
