I have one of those Gateway catalogs in my moldvay basic boxed set, but it's only a few pages.

This is an interesting theory - "information packet" is quite vague. Did TSR send out wholesale catalogs? I confess I know nothing about the publishing business, but it seems this could be a great many different things.

Funny you mention this, I"ve considered using a transparency spray to see what the cover page says. I presume whatever chemical this is (acetone?) would evaporate completely without damaging the envelope, but I'm also enjoying the ambiguity. My primary goal is fishing for information from others about what they think it might be.

That's awesome. Love the "Map Requisition Sheet"! Can you tell which artist the illustration is by?

The artist was Ken Frank

I have one of these open. I'll photograph and weigh mine and then you can weigh yours to see if they are the same!

That would be hugely appreciated!

I have looked for it but can not find it currently!

I had two adult children move abruptly back into our house and a mother-in-law downsizing and have 3 full sets of furniture stacked all over the place!

Hopefully, this all gets cleared out and I can get access to my collection!

Patience, I will find it.

Hi again - I totally understand if life ambushed you with some other obligations, but wanted to ping you just in case this slipped your mind. I'm definitely still very curious about those contents. I'm also curious about what the exterior of your envelope looks like.  (Another example on this thread was from a slightly later era given the exterior logo/appearance.)
