Back in the late 60s and early 70s it was difficult to get your hands on American pop music. At least, it was difficult if you lived in communist Poland. But Polish pop lovers found a way to get their fix of Donna Summer or Hot Chocolate. It came in the form of the sound postcard (pictured), a small plastic rectangle covered in grooves both literal and metaphorical. Poles would get a sound postcard in the mail, put it on their record player and gain access to unauthorized copies of western pop music, along with the occasional Polish tune too. We hear from Mat Schulz, an Australian living in Poland who happens to be a collector of Polish sound postcards.
