_"There are no more inventive people on earth than fly tiers, and tying dates back nearly 500 years. It seems that if it crawls, flies, leaps, or swims, fishermen have tried to emulate it, and have come up with some amazing attempts at recreating nature. Your particular fly seems to be trying to emulate a hellgrammite, and although I've seen a million flies in my day, I don't recall seeing this style before. It's very clever, and your father (or a friend of his) must have been an ingenious tier to make it. I have little doubt it would have caught fish. I'm guessing it was made in the 1960s, and I believe, because of its unique nature, should be valued at $10-$20. Now break out your vice and go tie one yourself!"
