This is an original 78rpm pressing. Note the absence of horizontal lines on the label.
Second pressing on blue vinyl. Note that the address spelling is the same as the 78 rpm version
(first-press 45s show a similar address but "45 RPM" is above the horizontal line). Also, the
paper used for the label is matte; third pressings used a glossier paper.
Third pressing on black vinyl. Note different address spelling. A quick check of the
deadwax matrix shows that both 45s were produced from the same stamper or mother.
