“It’s not that international any more. It’s too French,” said Nikolas Barta, an Austrian collector based in Vienna, who has been a regular visitor to the Paris biennale, as well as Art Basel, Tefaf and Frieze. Mr. Barta, 62, buys artworks from the 18th to 21st centuries. “And it’s a bit quiet,” he added during a somnolent Tuesday afternoon at the fair, when there were fewer than 200 visitors browsing under the cast iron and glass roof of the Grand Palais.
