Nelson Doubleday was the king of this type of illustrated booklet with inserts, as we've seen with the incredible Around the World Program for the American Geographical Society. We've got two more sets of these booklets to bring you, and we're starting with the Nelson Doubleday Personal Success Program. This first set is the covers -- check out the groovy backgrounds. This will be a fun series, as I'm also going to include the inserted practice materials. Enjoy the covers of the Nelson Doubleday Personal Success Program from 1958 below, or click through for the Flickr set.
