Not-Anokon 2
Not-Anokon 2 was a Minnstf fallcon, held 25–27 September 1981.
Documents from, and references to, this con are seriously hard to find, but we know the dates because DD-B took pictures there (see below) and dated them at the time.
Location
The Holiday Inn Capitol, St. Paul. This information had been lost, then hazily remembered, then confirmed in 2022 by DD-B, who says that it clearly says so on his contemporaneous notes for a roll of film he shot there. Oh, and now (2024), we've found a flyer for it, which confirms the dates and hotel.
Badge
Here are a couple that we have in the archives:
And here's one extracted from two photos of DD-B's (see below):
Photos
DD-B has a photo gallery for Not-Anokon 2 and FANPA has some more of his pictures from it. From them, you can see another example of the badge above, plus at least one other variety.
