A painting by Spanish master Goya has been stolen while en route across the US, two museums have announced.
Francisco de Goya is considered one of the world's greatest artists
The work was stolen near Scranton, Pennsylvania, said a joint statement issued by New York's Guggenheim Museum and Ohio's Toledo Museum of Art.
The 228-year-old work, Children with a Cart, was to be displayed in New York at an exhibition due to open this week.
Painted in 1778, the work is insured for more than $1m (£527,977). The FBI is said to be investigating the theft.
According to the museums, the painting was being carried by a professional art transporter at the time of its disappearance.
The insurer is offering a reward of $50,000 (£26,395) for information leading to its recovery, they added.
Francisco de Goya (1746-1828) is considered one of the world's greatest artists and one of the first "modern" painters. Children with a Cart depicts four colourfully-dressed children and a wooden cart at the base of a dark tree, with a billowing cloud in the background.
