The Telegraph: 91-year-old woman fills in crossword at museum - only to discover it was a £60,000 artwork:
"'Reading-work-piece', a 1977 work by Arthur Köpcke of the Fluxus movement, essentially looks like an empty crossword puzzle. Next to the work is a sign which reads: 'Insert words'."
The museum says "in the future it would alter the label for the work to make it clear visitors were not permitted to fill in the blanks." But Ann Althouse asks, "Doesn't that wreck the work of art?"
Rhett Jones says "Something tells us the Fluxus people would like this story."
