"The year after opening its new building, annual attendance at the Barnes grew from 60,000 per year to more than 300,000."

"Last year, 285,000 people visited."

Mentioned in Randy Kennedy's NYT story on Thomas Collins becoming the new director of the Barnes.  (Collins says "To me [the Barnes's move to Philadelphis] seems like an unqualified success. I have no reservations now about it at all,  and I wouldn’t be going there if I did.")
