GB Publishing was founded in 2023 by a mother & son duo with one goal: to create and publish engaging and unique adult and children’s coloring books.

This idea was expanded to include fun and entertaining children’s learning books, covering topics like math, handwriting, and reading.

We also decided to create all-ages activities & puzzle books with categories like mazes, cryptograms, Sudoku, and more.

GB Publishing has also branched out into print-on-demand design concepts, creating items such as wall art, pillows, mugs, clothing, fabric, and stickers.

All of the artwork utilized for Grumpy Bear products produced is created in-house by GB Publishing.
