The Sengbusch Ideal Junior Stamp Moistener is a vintage, American-made desktop item that is considered a piece of history. Its unique design and functionality make it a must-have for collectors. Gustav Sengbusch, a bookkeeper in the early 1900s, was inspired to create the Sengbusch Self-Closing Inkstand Company after an inkstand tipped and ruined a ledger page he was working on. His inkstands were designed to prevent tipping, allow one-handed access to ink, and prevent evaporation.
