This Valentine’s card, right, by the French artist Xavier Sager was posted from Finland in 1917 to an address in Norway. It is priced at £15 from Val Jackson-Harris, a dealer in printed ephemera from the 18th-19th and early 20th centuries.
Tournant dangereux (a dangerous turn) shows one of the roadster’s wheels coming off on a mountain road as the happy couple kiss in the back seat entirely unaware of the danger - as is maybe the wildly grinning driver.
Jackson-Harris, who is also chairman of the Ephemera Society, said: “Valentine’s Day cards are now hard to find in the UK as a great deal have been sold over the years to the States, but some dealers at the society’s fairs always have a few.”
