In this inspiring picture book, two friends explore the endless possibilities for what a museum can be, from a grand institution full of treasures to a tiny collection of one's own.

Museums come in all shapes and sizes.

Some are grand spaces filled with fine art and ancient treasures, while others are tiny, quirky, or wonderfully strange. Together, a young girl and her friend travel the world, discovering just how many different kinds of museums there can be.

Along the way, they learn that museums can be filled with all sorts of things. From butterflies to toys to books, a museum can be about anything!

Featuring real museums from around the globe, What's a Museum? invites kids to see the world as a place full of wonders waiting to be explored. With back matter packed with fun facts about each museum and where to find them, readers will be inspired to create a museum of their very own.
