Vintage printed paper document, WRNO Charter Listener certificate

The item is a printed paper certificate styled with a decorative black guilloche border framing the central text and graphics. The paper is off-white with black ink text and illustrations, featuring a stylized radio graphic at the bottom right that incorporates a banner reading THE ROCK OF NEW ORLEANS WORLDWIDE. The main header reads CHARTER LISTENER, followed by the typed name TODD WILLIAMS and the declaration IS A CHARTER DX LISTENER TO WRNO, HAVING VERIFIED ACCURATE. Further typewritten details note RECEPTION ON February 17, 1982 AT 04:30 GMT. A blue ink handwritten signature reads Joseph M. Costello III near the bottom left, and a small printed copyright notice reads 1978 Postal Instant Press at the lower left corner. There is a faint circular embossed seal impression visible in the upper left section of the certificate body. The condition appears well-preserved with sharp edges and clear text, though it is unauthenticated. The item reflects ephemera common to shortwave radio enthusiast culture of the early 1980s, functioning as a collectible verification document rather than a formal art piece. The identification rests entirely on the legible text and graphics printed directly on the surface.

Based on what I can see in the provided image, this paper ephemera item is a printed WRNO Charter Listener certificate bearing a signature attributed to Joseph M. Costello III and typed details for a reception on February 17, 1982. The certificate displays a decorative black guilloche border, a stylized radio graphic, and a faint embossed seal impression. I cannot verify from a photo whether the signature is hand-applied ink or part of the printing process, nor can I determine the exact paper composition without physical inspection. The condition appears well-preserved with sharp edges, which positively influences the estimate. Shortwave radio QSL cards and verification certificates from the 1970s and 1980s occupy a niche collectible market, appealing primarily to radio hobbyists and broadcasting history enthusiasts rather than mainstream art or document collectors. Demand is generally modest, resulting in accessible market values for items of this type. This value estimate assumes the item is a period-issued document as presented; however, an unauthenticated piece of this type would typically sell for less. To fully support the attribution and establish value, physical inspection by an ephemera expert and provenance research would be needed. If this piece turns out to be a modern reproduction, replica, or copy rather than a period-issued listener certificate, the market value would drop to nominal decorative or paper novelty levels, likely under $10.
