Actually, its supposed to be 26 3/4 x 38 1/2. I think you mistyped that one. Also, I don't think Bruce measures each one, but rather assigns one of the general format sizes. I think if he actually breaks out a tape measure, it will measure up. If this is from onesheetindex as Bruce says, there's no doubt it's real.
Now, for your drooling pleasure, here's the rolled one in my collection. I haven't seen it for years, and I just pulled it from the tube and shot this new photo. I'm really glad I got it when I did. As far as I know now, it's the only rolled one that's around, though I have got to to think there are others and that the owners just aren't talking about it. I've left the mounting board in the pic so that it's uncropped for you to view, other than the mag strips top and bottom.
