Here's a super cool development, I just received a custom backdrop for my freight yard wall. This is a custom work created by Joe Kunka in collaboration with Norm Charbonneau. The backdrop was created by combining a bunch of different photos of stuff on Norm's layout into a single long view.
It's going to take a bit to get the backing to install it, but I have a preview of what it will look like, Joe created the view by slipping a picture of the yard in front of the backdrop, pretty good match, it looks like a picture of the installed piece!
I'm blown away with how cool it looks, and I can't wait to get the real thing up on the wall!
My installation method will be to mount it on some thin Formica stock, then use construction adhesive to stick that to the wall. Trying to work over the yard with the bare vinyl backdrop and no backing seems like a recipe for disaster. I'm sure we'd put some wrinkles in it, and that would be a dirty shame! That's why I came up with the idea of sticking it to the Formica first flat on the floor, then handling it as a more rigid piece to mounting on the wall, I think the chance of getting it up there undamaged improves 1,000% over trying to put it up without a backing.
