You may find these Crazy Crawlers very often, but they're a little different. The eyes are painted in yellow and they have a black crossing mark around the line-tie eye.
Moreover, they have a round mouth and black abdominal muscles on the belly. These painting designs show they're a transitional model made during 1970-1971. Smith, a Japanese distributor of Heddon lures, once specially ordered a similar color in the early 1980s for the Japan market, but such lures have white eyes, not yellow ones.
Recently, I have got the smaller one, Tiny Crazy Crawler, in my collection (Thanks, Jim!). Very cute.
