A 91-year-old woman is under investigation in Germany after visiting Nuremberg's Neues Museum.
She took an art work depicting part of a crossword too literally and started filling in blank spaces on a crossword.
"Reading-work-piece," from 1965, was created by avant-garde artist Arthur Koepcke. It features the phrase "Insert Words" which the woman took as an invitation to action. The woman began writing on it using a ballpoint.
Museum Director Eva Kraus believes the work can be restored. The woman is being investigated for damage to property, although there is no suggestion of any malicious intent. The woman was reported only for insurance reasons.
"We do realize that the old lady didn't mean any harm," she said. "Nevertheless, as a state museum couldn't avoid making a criminal complaint. Also for insurance reasons we had to report the incident to the police."
The pensioner told police she understood the English-language instruction on the artwork to insert words and took it as an invitation to fill in answers to the clues.
The museum is full of interactive art, so visitors could be easily confused of what one could and could not do there.
