These tulips were painted by the nicely named  Rose Mead (1867-1948) in 1930. Here is her Wikipedia entry, she sounds an admirable person and what a wonderful detail this is: ‘During [her time at the Westminster School of Art in the 1890s] she painted herself cooking at a stove. A company that made similar cookers offered £500 (£39k in 2007, by now £45k) to add their name, an amount she refused because she was unwilling to “prostitute” her art.’
