The Parlophone and EMI logos printed on Australian Beatles record sleeves changed considerably between the early 1960s and the end of the vinyl era. Although EMI (Australia) had previously been slow to adopt new British corporate designs, from 1964 its sleeve branding increasingly followed developments in the United Kingdom. Locally designed sleeves provide the clearest record of this evolution, progressing from the circular Parlophone trademark to the EMI World device and, finally, the familiar stacked EMI/Parlophone logo.
