"This bamboo design is from the Royal Pavilion at Brighton (completed 1823) which was the residence built for George IV, Prince of Wales. This is about the earliest this motif shows up as an all-over wallpaper pattern. This paper was used in the Duke of York’s bedroom, George IV's brother. The Pavilion contained a great variety of wallpaper designs and this pattern was likely used as a border to accompany another paper. This intricate design of bamboo even contains trellis-work in the voids of alternating rows. "
