Note the periods in the spelling of "45 R.P.M." on the E-2 side.  In addition to the use of
punctuation marks the vinyl does NOT have a small (audible) bump in the groove at the end
of the song just before the runout.  Every other copy I've examined has the bump and spells
45 RPM w/o the periods.  The deadwax stamped matrix #s are identical, indicating that all
stampers were produced from the same mother.  Is this a true first pressing?
