This is all good information, but, back to the Crackajack issue, the books have no Dell branding, and the indicia publisher is K.K. Publications. GCD lists KK as Whitman/Western outlet, but are KK and Dell are not the same, are they?
GCD indicates that Whitman had three indicia publishers: KK, Western Publishing, and Whitman Publishing.
Of all the titles listed under the three publishers, less than a handful are GA, making me wonder if its worth the effort, but it seems that the Crackajack title is clearly not a Dell title.
