ValueTales is a series of simple biographical children's books now out of print. They were written by Dr. Spencer Johnson and Ann Donegan Johnson, and illustrated by Stephen Pileggi starting in the late 1970s.
I have 20 of the titles, as in the picture. The covers have labels from a church library that didn't need them anymore. The spines are a bit worn/sunbleached but the interiors look pretty well preserved! They are all first edition.
Individual titles are $5 or buy the whole lot of 20 for $70. Pickup only.
