I have two lines with letters and numbers in the lower right side on the back of the sleeve. Could either of those be the cat number? Also, the only date I see on it is on an insert in the sleeve. the date is December 31st 1985. I also recently found out that it is a Korean record, and I think that someone must have brought it with them to the country because it says on the back that the sale of the record outside of Korea is not authorized.
