I am glad I stumble upon her blog. The graphic designer and illustrator Blanca Gómez lives and works in Madrid, Spain. She created these whimsical and retro travel posters that feature the cities of New York, Paris and London---it's a project she did about illustrated cities for The Art Group.
The name of her blog---Cosas Minimas, meaning Tiny Things in Spanish. She thinks that name explains her work better than herself.
Love her style!
