Because so much of the hobby revolves around eBay, I've decided that it would probably be helpful to point to a few interesting auctions now and then. Tonight's eBay of the Day (or Night, DOWYA) is an auction for the paperback 1987 Update to the landmark 1985 Topps Baseball Cards book.
If you're unfamiliar with what I'm referring to, in 1985 the Topps Company released a large coffee-table book containing photos of the fronts of every card the company ever produced, up until 1985. The true 'revised edition' came out following the release of the 1990 set, but in 1987 Topps released a short, paperback 'Update.' The best part of the 'Update' is the inclusion of the 1951 Connie Mack All-Stars (absent from the 'revised edition' of 1990).
This is not my auction, nor do I care if it sells. However, if you've done your homework, you know that the two coffee-table books usually go for big bucks. The paperback Update; not so much.
