_"People have been trying to build a better frog lure for almost 150 years. What you have is a great mechanical frog--when you pull on the line tie, the rubber legs move. Froglegs was originally manufactured by Modern Sporting Goods of Austin, TX, which changed its name to Jensen and later moved to Waco. Early Jensen frogs were made of wood; yours dates from the late 1940s and is referred to as the Surface Model (there were a number of different styles). It came in at least six colors. In this condition, it would be worth $75-$100 due to the very early box. But as you rightly assert, it is priceless to you.
