About this work

This cut and folded tan paper model is made of four discs folded in half and fitted into holes in a perpendicular smaller disc. Hence Wheeler represents a sphere divided into eight lunes. A mark on the model reads: Dec-14-1915. A tag on it reads: 316. The model is, to use Wheeler’s language, collapsible.
