This guitar, known as "The Log", was later shown to Gibson executives, who initially passed on the idea of building them, but they changed their mind within a couple of years and the Les Paul Model guitar as we know it today was first released in 1952.
These early "gold top" models were later joined by the black Les Paul Customs, and then the sunburst "Standards" of the late 1950s.
