The above link goes to an article at The Scotsman. One of the treasures that will be on display in this collection is a tiny pair of miniatures in lockets painted by Nicholas Hilliard of Elizabeth I and Robert Dudley.

Here is a link to the National Galleries of Scotland. If you are unable to make it to the exhibit (like me!), there is a catalog of the miniatures available from the SNPG shop for £9.95.
