Girls guides were about the activities most girls were engaged in at the time, cooking, sewing, etc. You never would have seen a "Girls Guide to Shortwave Radio," for example, fifty years ago because practically no women were doing it. I am sure it would have delighted a small handful of girls, but that is not how markets work. You don't print a book if it is not going to sell. I generally disagree with your position on gender roles, which I think evolve naturally and are not necessarily bad.
