A Pablo Picasso painting has done quite the disappearing act in Spain this week.

The artist’s 1919 piece titled Still Life with Guitar has gone missing on its way to an exhibition at CajaGranada Cultural Center in Granada, CNN reported. The small work, measuring just five inches by 3.9 inches, was supposed to appear at the showcase starting October 9 but appears to have gotten lost in transportation; now, authorities are investigating how the painting slipped through the cracks.

The artwork went on a journey to get to Granada, one that is well documented. On October 3, a transportation van from Madrid arrived at CajaGranada Cultural Center to drop off various pieces, including the Picasso, the institute said in a press statement. From there, the artworks were shuffled all at once to a freight elevator, and then moved into the exhibition hall, which can be seen on video surveillance.

From there, the center’s exhibition manager signed off on the arrival of the packages, which would not be unwrapped until the following Monday. The works, which were still under video surveillance, sat unopened all weekend, with no unusual disturbances recorded. At 8:30 a.m. on October 6, the unpacking process began, but it wasn’t until midmorning once all the pieces were set about the exhibition room that the manager noticed the Picasso wasn’t there, according to CNN. The team then headed to the local police force.

“An investigation is currently underway, and the investigation is attempting to determine when and where the painting disappeared,” Granada police told the publication in a statement.

Still Life with Guitar, which is currently owned by a private collector, is ensured for about $700,000, or 600,000 euros, the CajaGranada Foundation told Reuters.

Even though all eyes are usually on Pablo Picasso’s famed paintings, that doesn’t mean one doesn’t go missing or get snatched on occasion. An oil painting that was discovered on a junk site in Capri over 60 years ago may have turned out to be an original Picasso, and two pieces were stolen from the artist’s granddaughter back in February 2007, among other various incidents. Hopefully, though, Still Life with Guitar won’t be missing for long.
