Harris has pointed out that in comparison with earlier designs by Adam for dressing rooms mirrors, such as the 1768 design for Lady Coventry's dressing room at Coventry House, Piccadilly (Adam volume 20/62), this design for a mirror frame (Adam volume 20/106) shows how much Adam's style had acquired a greater delicacy and attenuation.

It is not known if this mirror frame and pier glass frame were executed. If they were, then they would have probably been sold at auction following Keate’s death alongside his other effects, and are now lost.
