“The [Washington, D.C.-based] Corcoran Gallery of Art, testing new ways to regain its foothold as a high-profile Washington exhibition space, drew modest crowds to its recent sprawling exhibition on modernism. [But] the Corcoran increased its admission from $8 [to $14] for the show. The numbers… suggest that local residents and tourists are accustomed to free first-class shows. No matter how exquisite the exhibitions, museums that charge struggle to find a broad audience.”
