Paul Bunyan Dyna-Mite Lures

I don't know a lot about these lures other than they were my grandfathers and I never wanted to use them because they appeared so old. I'm guessing 1970s, but I'm not certain. I couldn't find a lot about these anywhere online except EBay and that isn't exactly the most thorough resource in my opinion. The lure with the box is # 901, and there are no dates on the box. The back of the box reads "Instructions: The Paul Bunyan DYNA-MITE lure is thoroughly tested and scientifically designed for casting (1/2 oz.) and spinning (1/4 oz.). To obtain maximum action the lure should be affixed to your line using a small snap swivel." And below that, it reads "For additional results and increased fishing pleasure, try a Paul Bunyan '66'." These appear to be wooden lures and they are both assembled with flat screws. I would love anybodys insight on these. Thanks!
