Design a captivating book cover for "Mary McMillan: A Life of Healing." Feature Mary in a vintage style, exuding strength and compassion, symbolizing her role as the "Mother of Physical Therapy." Surround her with elements that represent healing, such as medical tools and imagery of wartime rehabilitation. Include early 20th-century motifs, integrating scenes of her teaching the inaugural class of women reconstruction aides and her resilience during her internment in WWII. Use a warm color palette to evoke hope, determination, and resilience. The title should be bold and inspiring, reflecting her extraordinary journey of dedication, courage, and transformative impact on the field of physical therapy. Incorporate subtle textures to evoke a sense of history, inviting readers to explore her remarkable life story.
