Illustration Portfolio Review with Agent Marietta Zacker
Agent Marietta Zacker of Gallt & Zacker Literary Agency is offering the following:
- She will review your illustration portfolio (10-20 images).
- She will offer written feedback and insights on your work

Marietta Zacker has worked with books, authors and illustrators throughout her career—studying, creating, editing, marketing, teaching and selling. She supports independent bookselling, believes in libraries and takes pride in her work as a Latina in the world of publishing. She is always on the lookout for visual and narrative stories that reflect the world we live in, not the bubbles in which we put ourselves. She loves books that make readers feel and shies away from those that set out to teach the reader a lesson. Whether she is reading a young adult novel, a middle grade novel or a picture book, Marietta looks for a book in which young readers can identify with the actions and reactions of the characters, not the perspectives of the author or illustrator. Diversity in the story must be inherent and authentic, not trendy. She is thrilled to shine the spotlight on soulful, insightful, well-crafted, literary or commercial projects aimed at any age group from young adult to the youngest of readers. Books she will be championing in the near future include GIRLS LIKE US by Randi Pink, LATE TO THE PARTY by Kelly Quindlen, TRACE by Pat Cummings, LAND OF THE CRANES by Aida Salazar, I GOT NEXT by Daria Peoples-Riley, and MANHATTAN: MAPPING THE STORY OF AN ISLAND by Jennifer Thermes.
