The Artist Balladeer, model 1121, was introduced in 1970 as a shallower bowl version of the Balladeer.  The  Artist depth bowl (also shared with the Glen Campbell Artist and Country Artist models), is about 3/4 inch shallower than the deep bowl.  My guitar shown below is a 1970 model which features the 2nd generation winged bridge.  Other features include chrome Grover tuners, 5 piece neck, Sitka spruce top and MOP dot inlays.
