Scott Foresman Social Studies Grade 3 and Grade 4. 1979 series. See pictures. I can sell individually if preferred. Grade 3 has a very faint musty odor from being stored in outbuilding and faint age spotting on back two white pages. Message with questions. I think grade 3 can easily be aired out in the sun. Musty odors generally bother my allergies and this is so faint that it does not bother me. I just felt it needful to mention. 2 book total
