Champion Spark Plug Decals (not authenticated)

This lot consists of six rectangular vintage-style paper or vinyl decals featuring the iconic Champion spark plug logo. Each decal displays a distinctive bow-tie or hourglass-shaped central white field flanked by vibrant red on the left and black on the right, with bold, capitalized sans-serif black lettering reading 'CHAMPION' prominently centered across the middle. A small registered trademark symbol (®) is visible in the lower right corner of each piece, along with a small code reading '3-RA' in the lower left corner. The decals are arranged on a dark brown textured surface. The physical condition appears generally well-preserved with minor edge wear and slight surface dust, consistent with vintage or retrospective automotive memorabilia. The identification relies entirely on the visually matching logo typography and color scheme directly observable on the face of the items, though authenticity or specific production vintage remains unverified without physical inspection or archival provenance.

Based on what I can see in the provided image, this lot consists of six vintage-style paper or vinyl decals displaying the iconic Champion spark plug logo, complete with the '3-RA' code in the lower left corner. I must note that I am examining these items strictly via photograph, and physical inspection is required to determine the exact material composition, age, and production era. Based on the visual characteristics, if the assumed branding and vintage manufacturing are correct, comparable automotive memorabilia of this type typically trade in a modest range due to broad collector interest in petroliana and garage decor. However, I cannot verify from a photo whether these are period-correct vintage pieces or modern reproductions, replicas, or commemorative prints. The physical condition appears generally well-preserved with minor edge wear and surface dust, which supports a vintage appearance, but unverified items of this nature carry significant risk regarding authenticity. If physical inspection reveals these to be modern reproductions or copies rather than vintage stock, the value would likely drop substantially to a decorative-only range of $10-$20 for the lot. To confirm authenticity and establish a more precise valuation, I would need in-person examination by an ephemera or petroliana expert, along with potential archival research into the '3-RA' production codes to trace their manufacturing timeline.
