1939 Horlicks Poster Stamps, Huckleberry Finn

1939 Horlicks Poster Stamps, Huckleberry Finn, Tom Sawyer whitewashing fence is the lower right stamp on this set of 4 designed to be put into a Horlicks stamp book. I thought I knew a lot about fairy tales and Childrens stories until I tried to identify all of these stamps. I would appreciate anyones help in identifying these stories as we have passed them around and can't seem to find the answers. The stamps are unused, I have shown the front and back for you to view condition. The front and back is mint condition the glue is still on and they have not been used. This is a set of 4 including #37, 38, 43, 44 One shows Huckleberry Finn, Tom Sawyer whitewashing fence, one shows boy and monkey, one shows boy climbing out of window and one shows a pirate like Captain Kid or Captain Hook, there is a crutch, but you can't see his hands and the boy has clothing on like pioneer days such as Robinson Caruso era. These are connected (not torn apart), each stamp is 1 1/2 x 1 3/4"" and the sheet measures 3 3/4 x 3"" and are marked Storyland Stamp 1939 Horlick's
