This is a demonstration record - sometimes listed as "demo record" for short. Basically it's the same thing as a promotional copy. This one even has its finished picture sleeve, which isn't always the case with demonstration copies. The only real difference is that this picture sleeve is paper, whereas the original pressing picture sleeve is a thick card sleeve.
The only visible difference with the record labels is that "DEMO RECORD - NOT FOR RESALE" is printed on both sides.
The other really interesting thing about this demonstration copy is that it has both inscriptions on it, which can only be found on the first issue release. So, Side A has "We All Share The Same Air" and Side B has "Happy Anniversary To The P’s".
