Margaret Macdonald Mackintosh, 1864– 1933, was a Scottish artist whose design work became one of the defining features of the "Glasgow Style" during the 1890s. Her best known works include the gesso panel The May Queen, which was made to partner Mackintosh's panel The Wassail for Miss Cranston's Ingram Street Tearooms, and Oh ye, all ye that walk in Willowood, which formed part of the decorative scheme for the Room de Luxe in the Willow Tearooms. All three of these are now on display in the Kelvingrove Museum in Glasgow. In 2008 her 1902 work The Red Rose and the White Rose was auctioned for 1.7 million UK pounds or $3.3 million.
