We made small "stickers" to share with 'catters who showed up at the WVA Festival in 2001 using an enlargement from the .gif that's on the web page, "hand polished" in Photoshop Elements to remove all the overenlargement fringing and smooth the colors somewhat.
It's pretty crude, but might be useful if one isn't too fussy.
email on the way.
Sometime in the 2001 - to - now timeframe there was a thread discussing availability of a better file, with some info about where the icon came from and who had the "original;" but I don't recall that anyone came up with an "official" image file.
