The Overstreet Comic Book Price Guide to Lost Universes

The Overstreet Comic Book Price Guide to Lost Universes (2022–2024, Gemstone) is a two-issue miniseries that blends the authoritative pricing expertise of the Overstreet brand with a deep dive into forgotten or obscure comic-book worlds. Each issue explores a different "lost universe" of characters and concepts from publishers past, offering both historical context and current market valuations. While the series is brief, it stands as a unique archival project that celebrates the oddities and dead ends of comics history, guided by Overstreet's long-established reputation for documentation.
