Your memory serves you well, the aluminium cans did not take off until the late 70's early 80's when the technology needed to recycle them was invented.
Disclosure: one of the inventors on that patent is my father, his other research was in solar panels, ocean thermal engery (otec), the aluminum air battery , the use of adhesively bonded aluminum structures such as the Jaguar XJ and hybrid diesel electric vehicles.
