This design comes from John Willson's book "Mosaic and Tessellated Patterns" by Dover Books.

This drawing has 5 fold symmetry about the center. All the angles are multiples of 36 degrees. Yet, this is not a periodic drawing. Periodic drawing must have translation symmetry which is lacking in this design.
