This sleeve was made in Sweden by Polar and sent to some of ABBAs other record companies around the world. See USA Atlantic version where Atlantic placed a sticker of their logo over the Polar logo on the bottom right hand corner of the sleeve. It was made simply as a freebie to promote the record to press journalists.
I do remember reading about this in record collector magazine and was kind of irritated by the snobbish offhand reply as to the value of this item.
the promo looks like something perhaps included in a press pack for journalists at Eurovision 1974; Despite what the press release says, "People need love" did not chart in New Zealand or Germany, to my knowledge
Picture sleeve and press release sheet scans uploaded.
The picture sleeve has been manufactured using thick card that is very glossy. The package includes the Promo plus a press release sheet. I contacted Record Collector about 10 years ago to find out more and their reply was that although it is rare, ABBA vinyl does not command great value. Greatly disappointed, it had been stored away until today to share it with you all on 45cat. Anyway, the press release is a interesting read if nothing else. :-(
