When people frame the original Wacky art, often they do not have a mat cut. Without a mat , there is space between the surface of the art and the glass. Then the Letraset lettering sticks to the glass, and the art is never gonna be the same. Even the paint will stick to the glass if the frame hangs in a place where the humidity is high, so the solution to preserving this art is to have a mat cut for it when you frame it, and don't let the surface of the painting directly touch any other surface, especially a non-pourus surface like glass or plexiglass.
