Listen, if it was produced and published by Marvel's MAGAZINE department, distributed through traditional MAGAZINE channels, and sold through MAGAZINE shops and retailers, then it's a MAGAZINE, no matter what's inside.
That was the entire purpose of the Marvel Magazine line - to infiltrate traditional MAGAZINE distribution and retail channels to get the higher-end buyers and advertising.
Uh, what about Man-Thing's 1st App in Savage Tales #1?
1st appearance, yes. 1st comic book appearance, no.
That's not what the market thinks though. Admittedly, every story in Savage Tales #1 is a triumph in its own right, but it's still billed as the 1st app of Man-Thing (regardless of what you and Vince think)
CGC differentiates between the 1st appearance and the 1st comic book appearance apparently. Look at the label of an IH 272 for an example. I would suspect an Adventure into Fear 10 could be labelled as the 1st comic book appearance for Man-Thing if someone asked.
This isn't my opinion, but it does seem to be how CGC and several people think. Honestly, my opinion is it is a tactic to get more money from collectors. Look at Hellboy. There are 3 books a collector would need to track down to get all the 1st appearances.
If you've been following this thread, I'm firmly in the other camp.
Nothing personal but you "suspect" incorrectly, and no, CGC doesn't tailor its notes to the requestor.
