These paintings, depicting the Bishops and Peers paying homage to Edward VII at his coronation, clearly shows that not only was he crowned using the Imperial State Crown, not St. Edward's Crown.

They also show Edward VII wear the mantle that was made for his coronation in 1902, as George IV's has not returned to the Royal Collection.

The latter, Tuxen painting is also of note, as it shows clearly the King wearing the Supertunica and a Stole - as well as the Mantle - all seemingly embroidered.

I wonder if Edward VII's Mantle still remains within the Royal Collection, or whether this too was given away as "a perk".
