I wish I had my old Dr. Seuss books now, but alas, they went the way of most abandoned childhood things. So, I'm thinking of re-acquiring some. Here are some first editions. They're pricey now, so if you collect, seek out some slightly later editions. That's what I do with most books I collect, often going with later editions or later printings of firsts. Lots of early editions can be found on eBay. Heritage Auctions has some interesting editions, some signed by the author.
