It was a silent movie that was filmed around the San Francisco area. It used a color process developed by a fellow named Leon F Douglass, who also had a hand in the first Victor Talking Machines that played the old wax cylinders.
I assume the film is about Cupid taking a fishing trip, or perhaps about a love affair during a fishing trip, but I couldn't say for sure. It's considered a 'lost film', meaning no copy of it is know to exist anywhere & it's a safe bet that nobody around now has ever seen it.
So there you go: that's another little bit of useless trivia to impress the folks at your next fly tying gathering or fishing club meeting with!!
