Some strips we write the day before I draw them, but some sit in the hopper for many months, sometimes years, waiting for the right time to be drawn. Then I delete them from my scripts file, and move on. But once in a while I forget to delete it. That happened last week, and when I was frantically putting together Book 6 (announcement soon) I ended up making Saturday's strip a "cover" of a strip I drew last month. Well, that's embarassing. But it isn't the first time I've repeated myself - see if you can find the other cover (no, you don't have to write in - I already know which one it is).
