Local authorities are probing the case and reported evidence of an explosion, which caused considerable damage not only to the gallery but to the surrounding structures. The stolen artworks were intended for display and sale at the upcoming PAN Amsterdam art fair later this month. Warhol's Reigning Queens series, created in 1985, consists of 16 silkscreens showcasing the four queens, and has proven to be highly valuable, with two pieces from the same series fetching over £500,000 each at a recent Sotheby’s auction.

As the investigation unfolds, fingers are crossed for the safe return of these exceptional pieces that encapsulate a blend of contemporary art and royal portraiture, reflecting Warhol's lasting influence on the art world.
