There was a time, not so long ago, when museums were as inactive during the summer months as most TV networks. But today, with global art fairs and insanely high-profile events like the Venice Biennale and Art Basel dominating the summer scene, curators worldwide have no choice but to leap into the fray. With everything from Picasso masterpieces to little-known pen-and-ink drawings waiting to be acquired in Europe, the summer festivals have become a way of life for the wealthy art-collecting elite, and by extension, for the museums who depend upon the generosity of such collectors.
