Ten years after the 1933 photo of the Cadbury factory was taken, the same company published a profusely illustrated 56-page educational booklet for children, entitled "Our Birmingham". I have a copy of this, inherited from my father (died in 1961). I don't recall seeing this fascinating publication mentioned on the History Forum. Has anyone come across it before?
I've attached and image of the cover, plus a PDF of the introductory page.
