You can easily tell the reissue, because it has a different "inner ring" than the original. Here is the original
The reissue does not have the same 2mm concentric welt or circle. It has a thin single circle. Also the original (at least my copy) has a "Southern Music Sydney" stamp. But i can't guarantee that each and every original copy has that stamp.
Another difference I have noticed, is that the "45" at the top of the reissue label is not properly centered between the words "BY" and "FESTIVAL", that is
the original looks like this
BY
45FESTIVAL
but the reissue looks like this
BY
45 FESTIVAL
