Mona lisa has no eyebrows....

The Mona Lisa painting indeed has no visible eyebrows. This is historically accurate - during the Renaissance period in Italy (early 16th century), it was fashionable for women to shave or pluck their eyebrows. Leonardo da Vinci's painting reflects this aesthetic standard of the time. The current state of the painting also shows no eyebrows, though some debate exists about whether they may have faded over centuries.
