A New Geometry - STACK of TWO Vintage Hollow Books

Circa 1936 with previous owner notes all over the inside cover.  Super sneaky since this book won't draw interest from anyone but math geeks. Set of two made into one book safe.

  • Interior size: 6.75 x 3.75 x 1.45 in (height measured from top of arch)
