Maybe I don't really know the Bob Read bottle production. Because the bottle production I know -- which I thought sure was the Bob Read bottle production -- could definitely be done with a poster. Maybe it's not as elegant as with a draping cloth, but it's doable.
It can also be done with a beer bottle. John Lovick does it with a ketchup bottle, and even a highball cocktail glass (wearing a buttoned, double-breasted suit).
Perhaps, to accomodate these two factors, you have to give up some of what constitutes the essence of Bob's technique?
Regardless, I'm looking forward to reading it in Genii. It's a fantastic creation.
