If you're simply talking about vinyl-backed graphics, well they're a staple nowadays. They work OK if clearcoated, and if not, they eventually peel off. My Moto Team Champion frame of 1984 has the MOTOBECANE logo on both sides of DT and on the ST in vinyl, and they're all in pretty rough shape, with serious edge-peeling. Oddly, the "Team Champion" logo on the top tube is a true decal, and it's the only thing that's properly stuck, at this point -- everything else, including the stick-on foil-backed headbadge (which has lost almost all its color) has to be replaced.
As graphics, without clearcoat (which I prefer), the old solvent-fix decals were far superior. Though my Bob Jackson frame is quite faded and beat up, the decals on it still look great, even with patina.
If what you mean is raised plastic lettering, like a car dealership logo, then . . . never mind.
