Membership Card
Previously we called this a badge, but it is not. What's a "membership card", you ask? As per Mark Olsen in 2024, "The idea started very early. Conventions issued cards to each member. Sometimes they were filled out by the member, sometimes numbered and signed by the convention's secretary. It’s not clear that they actually did anything, but for decades they were part of the -- ritual? -- of joining a convention."
Program Book
Here it is in PDF (0.8 MB), or you can have one made out of the raw scans (72 MB), but probably you only want that one if you are on a fast connection and interested in the grain of the paper used. You can also see a text-only transcript (not counting advertisements). Finally, here are nice individual page images:
Flyer
Here's a flyer advertising the convention. It's a photo of the original marker drawing of the flyer. We presume that the flyer ended up being reproduced and used, but that's just an assumption!
