Question & Answer Series 186 Wee Books for Wee Folks Series

Q: Hi there, I’ve recently come into possession of a copy of The Robber Kitten. I was wondering if you could perhaps date this publication for me, or at least help me narrow down the publication period for me. I don’t really expect it will be worth all that much, simply because the dust jacket is so ratty, but I just kind of wanted to do some further research into the book for myself.
Any assistance you could provide would be greatly appreciated, thanks for taking the time to read my message.

A: This book is part of the Wee Books for Wee Folks Series, Format 3. This format was published between 1917 and 1931. Based on the dust jacket, the last title listed, Wee Folks Life of Christ, was published in 1920. So a fair guess is a publication date of 1920-1921. The ads in the back and the endpapers can also help with dating. This dating information is given here:

Value is hard to say. The dust jacket is in tough shape- maybe $20 or so.
