Fish 2023 Z Zone - Tour Fundraiser

Brand spankin' new, these Z Zones feature Fish's 2023 tour Fun-Raiser stamp, the Maryland Darter (Etheostoma sellare), a possibly-extinct freshwater species last seen in 1988, and, if still present, confined to an extremely narrow range of creek habitats. All of these discs came out pretty flat, and I expect will fly true to what a Zone is supposed to do--go a little ways then stable up in a hurry.
