Pierre-François Delafons|Louis Nicolas van Blarenberghe

This pair of artists made tiny, gem-like paintings you could hide in your palm—or drop into a snuffbox. Their specialty? Miniature landscapes so sharp you could count the tiles on a palace roof, painted on cream-colored vellum with a single-hair brush. A friend at the Met once pointed out their 1748 Chanteloup snuffbox, where every leaf and balustrade looks like a postcard you could tuck behind your ear. Because their work stays under glass, it’s easy to miss; but once you spot one, you start hunting for the next.
