The back cover of the Gibson 1975 Les Paul brochure gave specifications for two well established guitars in the Les Paul line: the Les Paul Deluxe and Les Paul Custom, both (re)issued in the late 1960s.
1975 was not a bad year for the Les Paul Custom, with 7451 guitars shipped - this was not the case for the Deluxe, however; although 2561 guitars shipped, this was a third of 1974's total and quarter of 1973's. Although only Gold and Cherry Sunburst are listed here as finish options, shipping stats suggest many other finishes were shipped this year (though sometimes in very small numbers): Blue Sparkle, Red Sparkle, Cherry, Natural, Tobacco Sunburst, Walnut and Wine Red.
January 1975 US prices for these models were: Les Paul Custom $710; Les Paul Deluxe $580.
