Large lot of both sealed and unsealed baseball cards, highlighted by two still-sealed factory sets including the 1989 Topps complete set of 792 cards, and the 1991 Topps "40 Years of Baseball" complete set. This is in addition to a substantial number of additional loose cards spanning multiple decades, from the 1960s to the 1990s, with a well-distributed mix of players, teams, and issues. The overall condition of these cards varies with typical corner and edge wear, and handling throughout. Some cards may present in finer condition than others. Additionally in this collection is two cards signed by former baseball player Norberto Martin. This is a sizable and historic lot of baseball cards from one very dedicated collector from a broad range of years.
