Antique Book - Dr Martin Luther's Smaller Catechism from 1868

This is a copy of Dr Martin Luther's "Smaller Catechism", in the original German, printed in 1868. It's not in the best of shape, but it's still a really neat looking, very old book. A Catechism is a text that presents the concepts of Christianity in a question and answer format. This one was written for the instruction of children.
