Nancy Drew books by Carolyn Keene are as popular as ever. Most know that these were not actually written by "Carolyn Keene" but were written by many authors under that pseudonym. The Matte Yellow Spine Picture cover format was printed from 1962-1986. These were the books that many read as children. Back then Nancy was often without access to a phone which is why she ended up in so much trouble, I suppose these have been re-written so that her phone is perpetually not charged! These yellow spines look great on any book shelf!
