If you happened across Richard's Poor Almanac this week (and you should every week), you would have seen the venerable Pat Oliphant's tribute to Richard. I know Pat Oliphant and he is not a man who throws around compliments lightly. Pat's greatest praise for me was "on time, at least."
This was taken from the introduction of the one and only Richard's Poor Almanac collection "12 Months of Misinformation" by Emmis Books and is now going for $650+ on Amazon for a new copy.
If you can't afford the book, you can see a good chunk of the contents in the archive at GoComics. It is work that will tickle your sensibilities and shock your disposition with how damn brilliant it all is. "Michelangelo with a sense of humor" indeed.
