Yep, it's a Hanimex logo all right, I found a couple of images on Google images, including one at 45spaces. Looking through Billboard, Festival first contracted with Hanimex in 1966 for reel-to-reel tapes, then adopted the Playtape system in 1967: I can't find anything to say when they switched to Philips' compact cassette system, but it was probably very soon after. Thanks Michael!
Hmmm - very odd of Festival to do that, and also to show their company name as just "Festival Pty. Ltd." when they used "Festival Records Pty. Ltd." on everything else! Makes me wonder if this is some sort of pirate release, and that other logo still isn't explained.
Hi PhilMH - the cat # should be correct as it appears on the spine of the case and the labels. I have added further images now. N.B. the back has the "Festival Australia" reference.
Hi Jasper, you've entered the US catalogue number; the original Australian LP number was SJL-933,258, in Festival's numeric sequence, so the cassette number should probably be SJC-933,258 or some other derivative of the LP number - although the H logo on the front makes me wonder if the label is actually something else (Horizon?) with an entirely different catalogue number style? And I can't help with dates for the cassette case.
