It's likely made in Japan, and like all the many others from the 1970s, that could mean just about anything. What I'm saying is almost all of these brands made very cheap copies, mid grade copies, and absolutely lights out top notch copies. So any given example could be cheesy beginner level, absolute pro, or somewhere in between.
The easiest thing to do here would be to look at the neck. If the neck is bolted on, then it's not necessarily a bad guitar, but it isn't going to be a fantastic one. If the neck is a set neck, and is glued in, then the likelihood of it being a very good guitar is much much higher.
Even with the set in neck, a lot of times the wiring and pickups were less than desirable on the Japanese copies, but that's just a guess for me here.
I guess if you were thinking about buying an Emperador Les Paul copy, I'd say maybe buy it were it set neck, don't buy it were it a bolt on neck. Pickups and wiring can always be upgraded, as can machine heads, but there's not going to be a lot of good reasons for fixing up an old bolt on neck LP copy.
