Museum Archive: Vintage Marathon (with sonic blades), fishing spoon #6821

Two small silver willow-leaf sonic blades sit at the base of the lure, intended to simulate the visual profile of a tail fin while reflecting light. Measuring 2 1/4" (6 cm) in length, the body features a striking green finish punctuated by yellow and red dots. Under dark conditions, the paint reveals a luminous glow while the spotted pattern remains dark for high contrast in deeper water. Marathon Bait Company, a prominent Wisconsin manufacturer active between 1929 and 1979, produced this specific model under product code 6821. The lure maintains a 4/5 condition rating, showing well-preserved paint and hardware for its age. The trailing blades add extra flash near the bronze-finished treble hook, which remains sharp and structurally sound.
