Well ... they're new for us, anyway. I've mentioned before how I collect Great Illustrated Classic books. My mother-in-law got me hooked on these books after she kept buying them for the girls. They are obviously abridged versions of the stories, but I've found they're great introductions. We've read many of these books in school, which lead us to reading the original full versions later on. I found both of these copies at a thrift store locally. I paid only a quarter for each one. You certainly can't beat that kind of deal.
I also found this book called I Love You, Mommy! It's a newer book from 1999. I guess that's not too new, but it is for me because I usually search for the vintage ones. It's a cute story, and definitely geared towards single moms who are involved in their kids' lives. I didn't see a father in any of the illustrations, aside from the picture frame on the cover. That got me curious, so I did a search and found the same author (Edie Evans) has a similar book called I Love You, Daddy! I imagine it's the same type, geared towards fathers who are actively involved with their kids. They seem like they'd be great books to read to kids of single parents.
I'm a huge Little Golden Books fan, and I've been working on my collection for years now. Just the other day I printed up a title list of Little Golden Books. I printed it in three columns, and it ended up being ten pages long! Sometime this week I want to get all my LGBs out and check them off that list. I doubt I will barely make a dent in it. Perhaps I'll post a photo with my results when I get around to going through them all. I'm curious how many LGBs there are in all. The Poky Little Puppy has sold over 15 million copies alone. One of my dreams is to have a story published as a Little Golden Book. Until I get an agent to get my submissions seen, that just won't happen. I'm not going to give up. Having a LGB is one of my goals in life.
