摘要

The infats play house (10) is a multi-coloured unit of polygonal cross section with a pyramid roof (12): each wall incorporating a door (14) opening into a three walled cell and requiring a unique key to open it: and each plane face of walls and roof incorporating shaped cavities (18b, 20b, etc). These latter are all of different geometric shapes and receive their own exclusive filler pieces, those in the walls being plain blocks and these in the roof being flanged ribbed units. Typical key heads are of different letter shape in cross section with matching key holes.
