As was to be expected, the RM/Sotheby's auction, which was planned around the Monaco Grand Prix Historique in May, also had to be canceled. A similar announcement will probably be made soon for the Bonhams auction. Without the historic Grand Prix, the auction would probably not have been able to attract the necessary audience, especially as it is unlikely that the coronavirus crisis will be over by then.
The auction houses are currently looking for new dates to be able to hold auctions with bidders on site again, but no one knows when the situation will return to normal.
