Fish 2023 Z Force - Tour Fundraiser

Brand spankin' new, these Z Forces 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. These Z Forces have a little dome but aren't especially stiff. Very see-through.
