(Previously posted, with a correction: HOW TO CARE FOR YOUR MONSTER)
You can see Geof Smith's ode to Norman Bridwell's classic book for creepy kids not only at the fantastic Frankensteinia site (see my links), but at Geof's interesting blog, The Connoissewer. It covers a range of topics, all with better commentary than you're going to read here at my little corner of the 'Net.
But first-- take a look at some photos of the Bridwell book never before seen on any blog!
(S' far's I know, anyway.)
I have yet to see a copy of this book that is in good shape; it's a sign, I think, that this book was well-loved and often read by its owners.
