Me, Frida by Amy Novesky, illustrated by David Diaz

From chapters.ca:
Like a tiny bird in a big city, Frida Kahlo feels lost and lonely when she arrives in San Francisco with her husband, the famous artist Diego Rivera. It is the first time she has left her home in Mexico. And Frida wants to be a painter too. But as Frida begins to explore San Francisco on her own, she discovers more than the beauty, diversity, and exuberance of America. She finds the inspiration she needs to become one of the most celebrated artists of all time. Me, Frida is an exhilarating true story that encourages children to believe in themselves so they can make their own dreams soar.
