These two generic bags turned up in a pile of 7″ singles recently, their utilitarian nature suggests they’d be off to land fill if I didn’t intervene! They would seem to be stock bags, issued by the labels concerned to shops so they could keep track of the stock bought and sold, along with other catalogue information. It’s the sort of routine work any record shop had to do to keep track of what was coming and going at a time of high sales. I would date them to the late 1970s on the strength of the slightly uneasy typography of the PolyGram logo which came in around 1976. Most shops made their own stock bags up using a white card sleeve, either just writing the information on or adding it to a sticker. There may well be others out there.
