1939 Horlicks Poster Stamps, Moby Dick,

1939 Horlicks Poster Stamps, Moby Dick, Peter Pan, Robin Hood and Gullivers Travels, 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 is mint condition and the back may have a little paper off or extra printing on it or not , just see photo as we used this template for all of them and some have nothing on the back. I still consider them mint condition as glue is still on and they have not been used. This is a set of 4 including #27, 28, 33, 34 One shows Captain as he watches Moby Dick the white whale blow his spout, one shows peper pan taking the children for a flight, one shows Robin Hood shooting his bow and arrow and one shows what I believe is Gulliver seeing the little people (no little people shown). 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
