I received 2 packs of 1989 Topps in the contest I won on the Autographed Cards blog.
Here are the results from Pack #2
Gary Sheffield(rookie), Don Heinkel, Ken Phelps, Houston Astros Team Leader, Dennis Eckersley, Kurt Stilwell, Chad Kreuter, Jeff Bittiger, Luis Polonia, Mickey Hatcher, Terry Clark, Charlie Leibrandt, Mike Scott, Andres Thomas, and Johnny Ray.
This pack was definitely the better of the 2 I received of 1989 Topps. You cannot go wrong with a Gary Sheffield rookie card. Eckersley is a Hall of Famer. And nabbing cards of Mike Scott and Andres Thomas are not too bad either.
