Mary Linwood was the most popular practitioner of needlepainting in England, and in fact she did meet Napoleon in 1803. Her embroidered picture is based on sketches she made at the time. In the same year Linwood received the Freedom of Paris.
This portrait of Napoleon was displayed in Mary Linwood's Leicester Square Gallery as number 52, in the 'Gothic Room'.
