This long running series (1904-1931) has three formats. The third format (1917-1931) is the most familiar with the grey covers, book appropriate appliqué and dust jackets that match the cover. Books were republished yearly so the earliest numbers are the easiest to find whereas the later issues are the most scarce. Thus the books published in 1930 and 1931 (#34-37) are hard to find since they may have been reprinted only once or not at all.
Here is Book #36- Little Miss Duck. It is written by A. E. H. and illustrated by Bess Goe Willis. It was published in 1930. Today I am adding the picture of its dust jacket to the database.
