[Kid stuff, but a reminder that early creative efforts can pay off if encouraged.]
Our special Christmas Issue. one of the drawbacks of the mimeograph process was that, if you happened to type on the wrong side - the two sides looked almost identical - your printed image would be reversed. So our special Christmas issue was special in two ways. We pretended we'd done it on purpose. The bottom block of text announces that this is also our "Special Backwards Issue," with instructions as to how to read it by holding it up to a mirror. Of course, those instructions are also backward. Soon I'll flop this image and post it so that you will not have to hold your monitor to the mirror to read this early example of Karl's writing.
Note the upside down Christmas tree; we were decades ahead of our time. It was not until last year, Christmas of 2006, that this notion began to catch on.
