In Australia, 15,000 official copies were released: 4,000 on burgundy 12" vinyl, 10,000 on CD, and 1,000 on cassette. There were two different pressings of the Australian CD, one with a silver CD and one with a blue CD. In Japan it was released on CD in large quantities. The Australian and Japanese releases have entirely different artwork. The Australian version is considered rare due to the limited numbers. There were only two official Japanese pressings, both on CD with barely noticeable variations in artwork. The Japanese CDs were rushed out without prior consent from the US parent company and as a result the cover art is taken from the inside artwork of the "Nevermind" album. All Japanese vinyl copies were counterfeit. Counterfeit versions of the Japanese CD's also exist and the Australian blue CD version has also been counterfeited. The Australian silver CD is the only official version of which counterfeit copies are not known to exist.
