"You've got one of the lures dating from the 1950s and 1960s with the greatest eye appeal (and neatest name): the Sail Shark. A plastic wiggler with an oversized dorsal fin, it was designed and built originally by the Demon Lure Co. of San Antonio, Texas. A cross between the Heddon Sonic and the Bayou Boogie, it was eventually purchased by the Lazy Ike Corporation of Fort Dodge, Iowa, who manufactured it for about a decade until it was discontinued sometime in the early 1970s. It's a cool lure made in a number of wild colors, and is very popular among collectors because it is abundant, relatively inexpensive, and has look. Without the box a Sail Shark is worth around $10-$15; double that with the box. Click here to see a comparison of the original and Lazy Ike version of the Sail Shark."
