I recently located the above article in the online archives of Box Office Magazine. What makes it exceptional is that it contains the only known photos of William Banks Levy and Hal Horne, both of whom played an important part in the early history of Disney merchandizing.
As you can see, however, this is a very low resolution image. I contacted Box Office Magazine but they do not provide high resolution scans.
Would anyone be able to locate a physical copy of the issue from June 17, 1939 which contains this article? If so, could you email me at firstname.lastname@example.org?
