$4,000,000 – $7,000,000 USD

Provenance History
Likely commissioned for a church in Tuscany (possibly Florence or Lucca); historical records suggest typical transitions through ecclesiastical collections to museum/gallery status.
Art Historical Significance
A major example of the High Renaissance synthesis of monumental form and spiritual grace. Fra Bartolomeo was a crucial peer to Raphael and Leonardo, influencing the transition toward Mannerism through his complex figure groupings.
Notable Features
The distinctive notched out-cut at the bottom center of the panel, likely designed to fit around a specific architectural feature or tabernacle in its original location.
Condition Issues
Visible vertical cracks (checking) in the wood support consistent with aging. Significant abraided areas in the sky/upper portion. Possible over-cleaning of the face of the Virgin and some minor retouching in the lower drapery.
Conservation Recommendations
Climate-controlled environment (stable humidity) to prevent further wood expansion; UV-filtered lighting; surface cleaning by a professional conservator to remove oxidized varnish.
