Gibson 1980 guitar and bass catalog. Page 29. Details of the SG Standard, which had a US list price at this time (July 1980) of $679.
The guitar pictured differs quite considerably from the example shown in the previous 1978 catalog: note the position of the pickup selector switch in relation to the volume and tone controls, and the new design intonatable bridge replacing the previous 'harmonica' version.
