Following the death of David Bowie earlier this month, fans of the music icon have flocked to the international Bowie exhibition, with ticket sales reaching the tens-of-thousands in the last week.

The Groniger Museum in the Netherlands – which is currently hosting the David Bowie Is touring exhibition – told Attractions Management that it has sold 30,000 tickets to the retrospective in the last week, a giant leap on total tickets sold, which stands at 50,000 since it debuted in December.

The exhibition has become somewhat of a memorial to the musician, with a condolence book for visitors to sign having recently been added and the museum opening its doors on the day of Bowie’s death to grieving fans.

The average number of visitors for the exhibition remain steady, according to a spokesperson for the museum, with around 1,000 per day visiting. But weekends are exceptionally busy, with the coming weekends, both on Saturday and Sunday, almost completely sold out. To accommodate increased interest, the museum has extended its opening hours on Saturdays, staying open until 10pm.

Groniger was the final stop for the Bowie exhibition, which debuted at London’s V&A in March 2013, before going on temporary display in countries including Canada, Brazil, the US, France and finally in Groningen, Netherlands.

The exhibition was originally scheduled to end its run on 13 March but with renewed interest following Bowie’s death, that could be extended. A representative told Attractions Management that at present it is “not yet certain” whether or not this would come to pass.
