I recently was given a copy of The Winged Horse Anthology published in 1929 (the eighth printing) by Joseph Auslander and Frank Ernest Hill (an excellent book!) Anyway, these notes were written on the very first page of the book.
By the look of it, I would say these notes were made by a student.
(I would click on the photo so that you may actually see it. Sorry the photo turned out so small :/ )
