1982-1986. Used for the black label.
Portrait was launched in 1976 as an Epic subsidiary with an artist roster that initially included Joan Baez, Burton Cummings, Heart. Ringo Starr signed up in 1978.
The following year the floundering label was ended with its only moneymaker Heart moving over to the parent label Epic.
Portrait was re-launched again in 1982, this time by CBS/Columbia, with a more current artist roster consisting of Cyndi Lauper, Altered Images and Sade. The label was stopped again in 1986 with some artists moving over to CBS Associated.
CBS re-re launched Portrait again in 1988 as a jazz label, ending by 1990. Epic took another stab at it in 1992, to no avail.
