If you're able to ignore the craptasticness of my folding job, that is. Not to mention the image itself. Anyway.
If the reference escapes you, you're missing out in a big way. Work on that. I think I started with Murder Must Advertise (which, granted, doesn't feature Harriet) and then went back to the beginning.
I suspect that I'll soon have a Bunter-related shirt, too. And one for Miss Climpson.
