Marguerite 'Gamy' Montaut (1883 - 1936) was a French artist who signed her work 'Gamy' and most of her work was produced using the pochoir process. She and her husband Ernest Montaut (1879 - 1909) created works of art focusing on the early transportation. Ernest Montaut began producing work in the early 1890s. Marguerite produced work focusing on not only auto racing but also early aviation. Marguerite is credited with the innovation of using lines behind vehicles to indicate speed, along with elongating parts of the vehicle to do so as well. She continued producing work after her husband's death in 1909. 'Gamy' is believed to be an anagram for 'Magy'.
