First two are standard size, just custom artwork. I couldn't find a rat image, but the "biohazard" symbol really works. The "pawn" seems appropriate to the minion ribbon.
Other size is for "wider" ribbon stock, hazelchaz and I talked about working with longer badge-extenders for things that call for extra text or artwork. Yeah, it's not the MICR (Magnetic Ink Character Recognition) font, but I couldn't find one and the old ribbons were the only location that used it (IIRC). I kind of like the 9-pin dot-matrix font, though. Techie and easier to read than the MICR text.
Better file mailed off to Chaz.
