I have learned so much about vintage fiction in the past few weeks. I started collecting old editions of Enid blyton recently on ebay and while browsing the different seller stores, I have learned about various vintage mystery series aside from Nancy Drew and Hardy Boys. I guess , after having spent years reading British YA fiction, I am starting to read American YA girls fiction, now officially past the age of young adulthood.
The Ones I’m really interested in learning more about are
Mystery Series
Trixie Belden Mysteries- Written and set from 1946 to the mid 1950’s.
Cherry Ames – Written during WW II to encourage girls to enter nursing.
Dana Girls- Series during the time of the original Nancy Drew series
Judy Bolton – Series set in the 1930s
Donna Parker-Late 1950’s and 1960s
Non Mystery Series:
Sue Barton- Nurse Heroine from 1936
Ginnie and Geneva-
Chalet School Series
Betsy and Tacey Series
Orange You Grape 
All the old stuff I wore as a child is coming back. Kinda scary and makes you feel old, but it looks great most of the time.
