"The Tender Time"

I'm reading "The Tender Time" by Denise Cass Brookman. It's a Best Loved Girl's Books book, published in 1958. Even though "TTT" is populated by kids who say "Gosh" and "Golly" and girls who find boys "dreamy," it's not badly written. Mrs. Brookman often transcends the genre, if only in brief flashes. I can imagine her composing something much more sophisticated and adult-like.
I'm just a sucker for the cover illustrations on books from the 50s and early 60s. I mean, look at Jim's eyelashes and Stephie's smile. And the way she's leaning into him. Dreamy!
