HarperCollins has posted the first 100 pages of Zot!: The Complete Black and White Collection by Scott McCloud
"I remember when Understanding Comics was first published in 1993 and Kitchen Sink sent me to a trade show to promote it. We’d sent out mailings, we’d taken out ads, but the best promotion for the book we ever did was simply handing out a thousand copies to retailers," McCloud writes on his blog. "Covers sell comics. Ads sell comics. But nothing sells comics better than the comics themselves."
