Museum Archive: Vintage Luhr Jensen Super-Duper 503, 1/8oz Frog fishing spoon #21637

At just 1/8 oz (4.3 g), this Frog patterned specimen showcases the classic 'U'-shaped metal design that made Luhr Jensen a staple in American tackle boxes. Measuring 1 1/2" (3.5 cm), the Super-Duper 503 features a deep green finish accented by three bold yellow spots with darkened centers. This specific Luhr Jensen lure, identified by Product Code 21637, was manufactured in the USA and maintains a very well-preserved state, rated at 5/5. The hardware includes a sturdy split ring holding a bronze treble hook, while the line-tie end is equipped with a functional wire snap. Originally designed to bridge the gap between a spoon and a spinner, this versatile piece is traditionally used for casting or trolling on light line when targeting trout, bass, or pike. The unique folding of the metal body allows it to catch water in a way few other lures can, which has made it a favorite for decades.
