Found a couple of old advertisements...
Bird cards! Yeah, all kids wanna collect Bird Cards!
And that Flycatcher looks SO damned happy. I guess when you're a kid getting Shredded Wheat for breakfast, birds cards are about the best prize you can reasonably expect. I can just see some little
advertising exec, crushed, sitting in his darkened office with his head
in his hands, wondering why it didn't work. It seemed so fool-proof.
Then there's this one, from the late 50's:
look at that hen gobbling down that Jello. I can safely say I doubt
very much if my chickens would EVER touch Jello. And they eat anything.
But Hickety's hep, all you cats.
