Moët & Chandon Brut Impérial Champagne Bottle — 1991 Monaco Grand Prix Dual-Signed by Ayrton Senna & Ron Dennis

Here's an auction-style description: Lot: Moët & Chandon Brut Impérial Champagne Bottle — 1991 Monaco Grand Prix Dual-Signed by Ayrton Senna & Ron Dennis A truly extraordinary piece of motorsport history, this authentic Moët & Chandon Brut Impérial Champagne bottle was present at the 1991 Monaco Grand Prix — one of the most iconic venues in Formula One racing. The bottle bears two highly desirable signatures: Signed in white marker directly onto the dark glass, the flowing, confident hand of Ayrton Senna is accompanied by the inscription "Monaco" and the date, making this an unambiguously provenance-specific piece tied to the legendary street circuit where Senna was virtually unbeatable — claiming victory there six times throughout his career. A second signature in bold black marker appears across the front label, attributed to Ron Dennis, the celebrated Team Principal of McLaren — the very team with which Senna dominated the era. Both the bottle and label remain in excellent displayable condition, retaining their original foil capsule and presentation. Items of this nature — dual-signed, event-specific, and connected to two of the most consequential figures of Formula One's golden age — are exceptionally rare and seldom come to market. A centrepiece acquisition for the serious motorsport collector.
