Thanks fer tryin'...
I'm familiar with the (Trinity river) 'Burlap' as I tie a fancier version of it called the 'Hessian Flea'.
I came across a photo of the 'Burlesque' in a "Fly Shop" (Redding CA) catalog as well as a photo of the same fly on Fly Depot's website...I just can't find the Rx or anything about the fly's history or origins.
It ain't a 'Showgirl', that's for sure...although I can understand how the names might get confused. Not that I have any personal experience with real burlesque showgirls. (grin)
