The little dwarf man in the Elfland

My fantastic children's story for ages 5 - 7 with 52 color images:

The little dwarf man is only five centimeters tall and his best friends are the little blue tit and the cute little mouse.

He has a few questions that his father can't answer. Only the elves can help him with this. He secretly sneaks away to fly with the little blue tit to the forbidden Elfland.
