Seems from 1990. Please refer to the link http://www.gibson.com/magazines/amplifier/1999/1/mainevent2.html PHP: The new '57 Classic pickup debuted in 1990 on several models with historic appeal, including the Les Paul Reissue. At the same time, Riboloff designed a new Les Paul model using the 1960 sunburst Standard as a starting point. The new model had the thin binding in the cut-away, the small headstock, various shades of sunburst finish and the inked-on serial number of the Reissue. But it had a slim, 1960- style neck profile, hot ceramic-magnet pickups with no pickup covers and "1960" stamped on the pickguard. It is clearly not a reissue. of the classic Les Paul Standard, although it was named, ironically, the Les Paul Classic. PHP:
