I came across this clip of J Fields Studio, which linen backed this Carter The Great poster, which measured 106 x 160 inches. They refer to it as an 8 sheet. There was recently some not so great reviews of J Fields (now called Papersmith) here on APF, but watching the backing process on something this size was the main reason I'm posting it here.
