Vintage puzzle ball toy designed by Peer Clahsen for Naef toys. A very rare
find, I reached out to folks at Naef and while they confirmed it the stamped
mark is indeed authentic Naef, they attested this ball toy was a rare piece,
possibly a prototype, that the staff and board was not personally familiar
with. Toy lays flat, and rotates into itself until it inverts from within.
Takes up a variety of sculptural shapes. Measures 5.25in wide x 5.25in tall
with 1.25in depth, each ball measures 1.25in diameter. Excellent vintage
