Print the image on white paper with a color laser or inkjet. It wouldn't hurt to do 2-3 of them in case they get messed up. Put the image upside down on a hard smooth surface and sand the back to make the paper thinner. The degree of sanding will make the image look different ages with different amounts of weathering. They will be fragile so take it slow and easy. When you are ready spread a thin layer of white glue on the side of the building and carefully lay the image right side out on it. Press out all of the bubbles and if it is a brick building press it into the brick seams. When it is dry spray some clear dullcoat paint on it.
I like to make my own decals. I print them on my home computer's inkjet.
But, normal printers don't print white at all, or light colors very well. They assume you are printing on white paper. So, I paint the appropriate shape in white paint on the building, and apply the decal over the paint. I'm not a terribly tidy painter so I usually edit the image and add a thin dark border on the edges to cover up irregularities in my painting.

Hi, Bernie
I recall that article. I'll look it up when I get a chance. Seems to me that you printed a reverse image then coated it with a PVA type gel or something to apply it to the structure.
In the meantime there is a thread here (Photobucket took away some of the images) that shows one method.

In the text of this thread I mention the gel-transfer M-R article that appeared in the June 2016 M-R.

You'll also find a link to TomKat-13's Facebook page where he has made hundreds of handy signs available.
I don't know anything about Facebook but I believe you can see them without having an account there? (When a "sign-in" window pops up click on "not now!)
Good Luck, Ed
I want to transfer old advertisements onto buildings. I know thwere was an article once in M.R. I cant find it and when i did a search. I got into the a never ending circle. If anyone knows an easier way to transfer or knows of thearticle. It would be a great help. I have GIMP and Sketch Up.
