I’ve added a book to my collection that may be one of the oldest I currently own. Clocking in at around 92 years old (and being a second edition of a book that would be 102), it’s a “guide” of sorts for how to write/tell stories for/to children.
It’s in remarkably good shape for a book of its age, and I got it for a steal. These antique stores often have little understanding of their value of their merchandise.
