Museum Archive: Vintage Marathon (with sonic blades), 2/5oz Blue / Nickel fishing spoon #7111

Weighing in at 2/5 oz (12 g), this casting spoon features a distinctive blue scale pattern surrounding a central holographic diamond insert. Found in the catalog under product code 7111, the lure measures 2 1/4 inches (6 cm) and showcases the unique design philosophy of the Marathon Bait Company from Wausau, Wisconsin. The company successfully produced tackle for fifty years between 1929 and 1979, and this specimen represents their specific variation featuring two elongated silver mini-blades attached to the split ring. These sonic blades are positioned alongside the treble hook to catch light and provide a visual representation of a baitfish tail. While the front is vibrantly textured, the back side is finished in a clean, polished nickel. Stamped clearly on the small sonic blades is the Marathon name, providing a reliable mark of authenticity for collectors. The finish on the face is well-preserved and the hardware remains robust, earning this vintage lure a 4/5 condition rating. It serves as a solid example of mid-century American manufacturing, combining a textured blue-green body with light-reflecting elements to attract strikes while casting.
