To Gogh? — or not to Gogh? — that is the question.

The highly anticipated opening of “Immersive Van Gogh” has been postponed by at least a day, organizers said, because the show hasn’t yet received its certificate of occupancy from the Los Angeles Fire Department indicating that the building meets fire code standards for large numbers of visitors.

About 2,500 ticketholders were expected to attend the opening Saturday in the former Amoeba Music building on Sunset Boulevard. Organizers from Lighthouse Immersive and Impact Museums said they plan to send an email Friday afternoon to ticketholders, who can choose to be fully refunded — tickets start at $39 — or reschedule their visit “at the date of their choosing,” representative Shelley Reinstein said.

A media preview that was to take place Friday morning also was postponed, according to an email sent out late Thursday night.
