...Oval white label as used from spring 1947 to January 1955.
...Orange label as used from January 1955 to 1964. The 1964 to 1969 orange labels are identical, except for the added text "union made". Note the faint ink stamp along the bottom of the label denoting "STEREO VARITONE" (though non-union made labels are seen later).
...Orange "union made" label as used from 1964 to 1969. Note the "union made" designation to the left of the "Gibson" insignia. When Gibson was bought by Norlin in 1969, thousands of these labels were discarded (and replaced with white and purple "Norlin" labels). These blank unused labels were snatched up by many guitar dealers, and are still available today.
...White label used from 1908 to 1932. This particular label is from a 1929 L-4 model.
