This is a strange one. I bought it in a charity shop, & thought it was probably a bootleg. Since however , I've found out that Euroton is a Croatian label, but that's about all i can find out. Maybe somebody out there has some more info. I Would also imagine if this is a genuine release it would have been released Europe wide.
It says J.S.. Records on the sleeve, but I can't find any info on them so i've classified this as a bootleg. Even the sleeve doesn't look very professional.
