This lovely tiger lily plate is from a book of botanical plates and images from 1878, so they are out of copyright and free for you to use however you would like. I love the bold look of tiger lillies and they add a nice burst of color to any project-- try adding them to something with a lot of blue; orange and blue are complementary colors so they will accent a blue page nicely!
