I pic came up recently in one of the fora, maybe this one, showing a late '80s Epi with a Gibson style "open book" headstock. When did they change to the current design, and did it coincide with moving production to Asia?

I've no particular reason for asking, I'm just curious.

The Epiphone Les Paul Standard was first introduced in 1989 and was originally made at the Samick Plant in Korea. Although not Epiphone's first Les Paul model, the 1989 Standards and Customs were their first Gibson-licensed set-neck Les Paul that closely resembled the original model. Prior to 1989, Epiphone's Les Paul offerings were in the form of the LP-1, 2 & 3 bolt-neck models and a practically unknown Studio-type model with a set-neck and a flat top.

The 1989 models were the first to sport a set-neck and a carved top with a cap. Like the previous 1986-1987 LP models, the 1989's came with the Korean version of the open-book headstock. 1989 was the last year the Epiphone incorporated this headstock onto their guitars, with the exception on the 1990 SQ-180 acoustic guitar. Japanese and Chinese domestic models used a different version of the open-book headstock for a brief period of time. Currently, all Les Paul models have the modern "clipped-ear" style headstock.
