You'll find works by Raphael, Rubens, Fragonard, Rembrandt, Tiepolo, Van Dyck, Poussin and many other masters in the National Gallery of Art's exhibition of Old Master drawings from the collection of the National Gallery of Scotland in Edinburgh. The drawings were selected by Hugh Macandrew, keeper of prints and drawings at the National Gallery of Scotland, and Andrew Robison, senior curator at the National Gallery. And although for various curatorial and legal reasons there are no British or German drawings in this show, the breadth and scope of the works included make it clear that the National Gallery of Scotland's is a magnificent collection indeed.
