Hi! I’m Marta Piedra — a passionate illustrator and lettering artist with a background in graphic design, a knack for computers, a pinch of humor and a little bit weakness for coffee and animals.

I’m a Spanish graphic designer and lettering artist focused on editorial work and book publishing. I create expressive, type-led illustrations and visual identities for book covers, series titles, and branded narratives. My work blends bold aesthetics with thoughtful storytelling, and I’ve collaborated with publishers like Penguin Random House, Alfaguara, Larousse and Salamandra Graphic.

I adapt my visual style to fit the tone and audience of each project, but there’s a consistent thread throughout my work: a strong sense of composition, expressive typography, and a narrative-driven approach that makes each piece unmistakably mine.

Her ability to tackle new challenges and bring her magical brushes to the team are the two virtues I highlight from this professional experience, not to mention her ingenuity and disruptive vision, spiced up with bursts of humor and a touch of playfulness during those early morning chats while she walks her dogs. It’s a pleasure working with Marta!"
