This just in from Gunnat Andreassen:
[Here's an English article MICKEY MOUSE and HIS MASTER, from Film-Lovers' Annual.
Probably the 1935 annual, published in 1934.
The initials of the author are M.D.P. I found another article in the same annual written by Malcolm D. Phillips, so I guess that it must be him that wrote it. I have found a person on the net who wrote an editorial in an English Film magazine in the 30s with the same name.]
