Holy crap Rick! I didn't think anyone would get it! Well Done! (you too Marco)
It's Paph. Leslie 'Tommy Miller Cox' AM/AOS (sukhakulii x exul) awarded back in 1983. This flower is nowhere near as impressive as it is in the award slide, but this is the first time I've seen it bloom in person. It always amazes me just how dominant sukhakulii is as a parent, even when in the background of a complex hybrid.
