This is a 19" CRT monitor underneath a 9.5" x 32" OK button. If you click on the photo and follow the link to the bigger picture, you'll notice that the resolution on the OK button and the accompanying finger doesn't seem to get any better. That's because it doesn't.
They are printed on regular old 8.5" x 11" paper, and then glued down to foam core. I can take my OK button anywhere.
