This book is obviously a reprint- it has 14 dolls and only 4 pages of clothes. The outfit breakdown is odd- J, P and T have 3 outfits each. A, R, and I have 2. S, H, N, O, K, M and E have only one apiece. And poor little C has none at all. I'm sure these dolls and clothes were part of a much larger set originally. This version was published in 1941, it's Saalfield's #1958 Outdoor Dolls. The artwork looks a lot more mid-30's to me, and I expect that the first set was published closer to that time.
