Ok, Uploading "Dell_Scribbly.cbz" even as I type this. The file contains the Scribbly comics (no ads or contest pages) from the following issues:
Popular Comics 6-9
The Funnies 4, 8-14, 16-19, 22-26, plus the covers to 21 and 26.
With the exceptions of the Popular Comics and The Funnies 4, 9, 12, and 26, all scans are by me. I don't know who did the others for sure; I believe Teto7totoro did some. (I have a comicless copy of the cover to 21; since it's the first Scribbly cover it's pretty much the only comicless cover where I actually care that I have a copy.) If anybody has copies of the Scribbly pages from The Funnies 2, 3, 5-7, 15, 20-22, 27-29, or better copies of the #26, I would love to see them so I can upgrade the file. It's still 38 of the 65 pages of Scribbly material Mayer did before moving to DC; and I personally think the material gets even more impressive when you have enough to see the continuity Mayer was working on.
