Oh yes! It is a brilliant book! I had a quick lookthrough this weekend in the book shop and there is a whole page just for dwarven jewellery! It is exactly what I had hoped creatures and characters would be (which only has photographs and filmstills but no concept sketches). I will definitely get Cloaks and Daggers for Christmas. It focuses on the realised props and shows them in great detail!
And yep they definitely tried to link the royal dwarves through their costumes and accessories.
