For 1976, the Continental Mark IV debuted a new tradition, called the Designer Editions, which later spread to other models in the Lincoln model range. Introduced as four special-edition models, each edition was an option package with color, trim, and interior choices specified by notable fashion designers (Bill Blass, Cartier, Givenchy, and Pucci). Each edition carried the designer's signature on the opera windows and were fitted with a 22 karat (92%) gold-plated plaque on the instrument panel which could be engraved with the original owner's name. The concept was successful and would continue on other Lincolns until the end of the 2003 model year.
