THE HAGUE, Netherlands (AP) — Thieves blew open the door of an art gallery in the southern Netherlands and stole two works from a famous series of screen prints by American pop artist Andy Warhol and left two more badly damaged in the street as they fled the scene of the botched heist, the gallery owner said Friday.Mark Peet Visser said the thieves attempted to steal all four works from a 1985 Warhol series called “Reigning Queens,” which features portraits of the then-queens of the United Kingdom, the Netherlands, Denmark and Swaziland, a small landlocked kingdom in southern Africa which is now called Eswatini.In a telephone interview, Visser said the heist early Friday at MPV Gallery in the town of Oisterwijk was captured on security cameras, and called it “amateurish.”“The bomb attack was so violent that my entire building was destroyed” and nearby stores were also damaged, he said.

The heist was described as ‘amateurish’.

Two works in the Reigning Queens series were taken, according to the gallery's owner.

The pictures were from Andy Warhol's "Reigning Queens" series and depicted UK’s Queen Elizabeth and Queen Margrethe II of Denmark.
