I'm not entirely sure which specific 'my block book schoolhouse of bible stories' you are referring to. It could be a unique collection of Bible stories presented in a block - book style, perhaps used in a school or religious education setting.
Probably not. There are so many different compilations of Bible stories out there. Unless it has some unique features or was very popular in a specific region or community in 1970, it's likely not well - known on a large scale. It could be a local or personal publication that didn't gain much broader attention.
You can try 'The Children's Illustrated Bible'. It has beautiful illustrations and simple retellings of many popular Bible stories that are easy for children to understand.
It depends. While many images in a book of bible stories aim to be accurate, sometimes artistic license is taken. But generally, they should be close to the essence of the stories.
