London - The restoration and complete overhaul of a 15th century copy of Leonardo da Vinci's Verging On The Rocks has revealed a new version of the Mona Lisa.
Sitting surrounded by Stonehenge's awesome monoliths the Florentine beauty wears a crimson bejewelled robe similar to that worn by Da Vinci's Salvator Mundi.
Behind her the Winter Solstice sun shines through a gap in the circle's standing stones illuminating an aura of blazing rays behind her beautifully coiffed tresses.
"Gotta be worth at least half a billion dollars," curators of a Mayfair art gallery charged with the picture's overhaul said today as news of the find became public.
Of course the painting's existence had been suspected for centuries following the discovery in 1503 by Agostino Vespucci at Heidelberg University of some heavy hints about the picture in a note scribbled inside a book on alchemy.
The Florentine chancellery official was an assistant to Vatican arch-fixer Niccolo Machiavelli and claimed the Stonehenge Mona Lisa was painted for the chapel at Salisbury's Catherdral Church of the Blessed Virgin Mary.
The awesome ecclesiastical edifice lies some 12 miles south of Stonehenge and was built in the middle of the 13th century by stonemasons working for forerunners of the Illuminati.
The portrait's ownership remains shrouded in secrecy amid claims it was an Antiques Roadshow reject from circa 1987.
This weekend it has been reported to be on 24/7 armed guard at an underground vault used by the MoD for storage of 'alien' artefucts.
Plans to exhibit the 8ft x 6ft painting later this year are subject to concerns following insurers' draconian security demands.
An update follows later.
