A damaged Georgia O’Keeffe painting is back on display after conservators spent over 1,200 hours and $145,000 restoring the piece.

One art expert with the Georgia O’Keeffe Museum calls the job the biggest restoration project he has ever worked on.

Conservators had to repair not only water damage but previous restoration work that had failed.

The painting, titled Spring combines several of O’Keeffe’s favorite New Mexican subjects.

The results will be on display at the museum through October 10.

The painting will then travel to the San Diego Museum of Art  next year.
