L&S Bait Mirro lure

L&S Bait Company, Inc
It all started in 1933 when Harold LeMaster, searching for the perfect lure, handmade a jointed wobbler from walnut wood. He named his invention "LeMaster Shiner Minnows." This lure quickly proved highly effective for catching large Bass and Walleye.
LeMaster began commercially trading his lures in 1937. In 1941, he was joined by partner Phil Schriner. After World War II, in 1946, they officially opened the L&S (LeMaster & Schriner) Bait Company. That same year, they made a pivotal move toward the future by introducing their first plastic lures.
In 1950, L&S opened its Florida division, focusing on saltwater fishing, initially known as Mira-Lures. This division was later rebranded as "Mirr-O-Lures" (and eventually MirrOlure).
The MirrOlure line quickly achieved iconic status in inshore fishing due to its main technological innovation:
Unlike conventional lures, the MirrOlure body was made from clear or translucent plastic, housing an internal reflective foil.
This foil created an effect of deep, internal light and shimmer, which very realistically mimicked the scales of a wounded baitfish reflecting light underwater. This feature is the key to its success in attracting saltwater predators.
