I have three books:
"A Primar of Essentials in Grammar a Rhetoric" by Maritta Knight unlisted by American Book Company in 1905
Milton's "Paradise Lost" illustrated by Gustave Dore. No publisher or date, but my mother-in-law's signature and the date 1928
"The Moonstone" by Wilie Collins published by Harper & Brothers, Publishers, Franklin Square. 1868
Any idea if they're worth anything? Peg Fisk
