The first issue Canadian cassette release for the Mini LP differs in some specific ways to the second issue release, especially with the insert. You can check the more obvious differences out by clicking right HERE.
The first issue insert is double-sided, whereas the second issue insert is one-sided only. The reversed side is nothing to get excited about as it's just a rant about cassettes and cassette care stuff,
The first and second issue cassettes both have the same catalogue number, and the cassette shells are fairly identical, except for one little difference. The second issue cassette has "Made in Canada" stamped into the edge of the cassette on the A Side, but the first issue cassette doesn't have this at all.
