Funny what you find on Google news - this story about the purported Giotto crucifix of Ognissanti is news to me:
"The Ognissanti Crucifix, believed to be the work of early Renaissance artist Giotto, was presented to the press after undergoing an extensive restoration, in a lab in Florence, Italy.
The crucifix, which normally hangs in Florence’s Ognissanti church, had been attributed to “a relative of Giotto” until just over a year ago when researchers questioned the attribution after a cleaning of the paintwork."
