My 6 yr old son really loved these for story time. Nothing scary in this book, but there were a few stories that seemed very dated, and some which were even culturally insensitive in their portrayal of native Americans.
There were points where I chose to censor or revise while reading to him. But most of the stories were actually well intentioned and even progressive for the 50s or whenever these were written. Multiple stories had strong female leads, many had compassion for animals as a central theme.
Otherwise I thought the inclusion of poems and art made the book kind of charming.
