The cover, which you can view below, was one of only 100 hand-painted by Banksy himself, back in 2002.
It sold for $10,256 (over £8000), making it the highest-priced sale ever seen on Discogs.
The cover shows the duo’s name in a standard green, stencilled font. Below it is a green design that look like pixellated treetops.
Royksopp’s debut album was a huge success for the Norwegian band and peaked at Number 9 in the official UK albums chart.
Last month, Banksy launched his very own online store, selling iconic items from as little as £10.
Many of the products advertised featured at a recent art installation in Croydon, which has now closed even though it never officially opened.
Royksopp last released their final album the ‘Inevitable End’ in 2014. They have since continued to release one off songs including 2016 single ‘Never Ever’.
The song featured Susanne Sundfor, who previously featured on the songs ‘Running To The Sea’ and ‘Save Me’ on ‘The Inevitable End’ and Royksopp’s cover of Depeche Mode’s ‘Ice Machine’ from their ‘Late Night Tales’ compilation.
