I don't collect old newspapers, but I made an exception in this case.
The Sunday Mirror was distributed in New York, and this issue is dated 12/26/37. The '16 pages of comics' were not in there, but that's ok. The back cover is what caught my eye.
I remember Overstreet noting an issue of Mickey Mouse Magazine that has the 1st appearance of Snow White, before the movie release, maybe the first time in print anywhere. I doubt this paper pre-dates the magazine, but it did come out before the movie. It's also different to read about Walt Disney and his accomplishments in the present tense.
