Specialty

The reissues on Specialty can be quite a problem because of the label similarity, and because the
dead wax information is identical.  Most recent reissues can be identified by the rolled edge at the
lead in groove, the originals are flat.  In some cases there is information on the label pertaining to
an LP that did not originally appear.  The wax of many originals had somewhat of a used appearance
even when new.  The prefix 45-SP was used extensively in the dead wax of originals.
