This is a feature added to Better Little Books® in an attempt to increase sales. The feature was introduced late in the third 1400 series (mid-1941) with directions showing how to hold the book to flip the pages. In the upper right-hand corner of each right-hand page was a set of illustrations which progressively showed motion as the pages were flipped from front to back.
Nearly all the titles in the fourth 1400 series (1941-1943) contained a flip-it feature. Interestingly, some of the flip-it features in this series are left-handed. Some ads show the pages being flipped from right to left, others show from left to right. Some books have two flip-it features. The feature was discontinued after this series.
