Here’s some fun custom wallpaper we did for a customer in New York City for their lobby. They used a greyscale photo of the New York skyline, and superimposed it onto multicolor backgrounds. The stuff you can do today with Photoshop!
Each panel is 4×8 feet in size, making a total mural dimension of 8×12 feet. We shipped them three sections of wallpaper each fifty inches wide, with two inches of overlap so the edges can be cut to match perfectly.
This is a pretty typical lobby installation. The wallpaper took us a few days to make, and it took a day to be installed.
