Always anomalies with Aussie posters, but as above, there is a chance it was a video poster, I really don't know. I didn't delve as these films have no interest to me. And I was only collecting then, so info for knowledge sake alone wasn't so important, if it wasn't something I would buy.
Anyways, seems after all this time, there is no image on the net, so fingers crossed Keith's son remembers it, or even better still has one or more.
