At some point in “Ginevra de' Benci’s” history, before 1780, the painting was cut down, presumably because of damage. The truncated wreath on the reverse supports this idea.
This silverpoint drawing from The Royal Collection at Windsor Castle, provides an idea as to how the portrait may have appeared before it was cut down. Did this drawing serve as a preparatory study for Ginevra's portrait? A reconstruction of the portrait (right) helps us imagine the original format.
