Blocks
Young children want to build but their fine motor skills needs to develop. Solid blocks for solid constructions. The smaller the infant the larger the blocks.

Building, stacking and rollovers. The child is experiencing weight, balance, shape and colour difference. The blocks are splinter-free, non-toxic finished and baby-proof manufactured.

1952 Wooden Toy Block Wagon

Size: 42 × 23 × 8 cm
During the course 'Cursus Industrial Design', Van Blokland designed this wagon with blocks which can be fully dismantled. Gerrit Rietveld formulated the assignment to design toys as: 'Toys where the package becomes part of the playing'.

Building with parts

The wagon has been constructed without nails. The wheels of the wagon can be taken from one side of the axis which allows the coloured long blocks to be part of the game.
