I am not sure but I started to collect "I grandi del Jazz" series, it was sold in newspaper kiosks and was really cheap, one third of LP normal price. It had stuff from Atlantic, Verve, ecc, among them I remember well Olè Coltrane. And then there were Prestige twoofers, The Davis Quintet, Monk, etc.. They were cheap and available in all record stores. In the late seventies it wasn't easy to find jazz records in small town in Italy.
