I have this as well. It's a French cassette (Cat.no. 661111 4) issued by Helter Skelter, and very rare. It was first featured in an article in Record Collector magazine in the mid-nineties, but it actually took a few years till I saw it offered for sale. The weird thing is; in recent years I've seen quite a lot of listing of it from Thailand on eBay. I would be a very skeptical at this, but what's even weirder is that they look legit/genuine. I will have to compare them some day. Either way, at $10 it's a steal.
Where was your seller from, schorman?
PS: I will be doing an article on all French promotional items for my website this autumn, as Oasis issued a lot of rare items there that are very difficult to find (football shirt, record bag, etc..). Will dig into the story of that cassette as well.
He was from Thailand. My guess is it was released there as well. Most likely not a French release, though there's no indication on the insert or cassette. All indications are that it was a French release. I guess it could have been imported there, you never know.
If I had some gum, I'd chew a hole into the sun...
