Editing Topps (section)

===Use of statistics===
One of the features that contributed significantly to Topps's success beginning with the 1952 set was providing player statistics. At the time, complete and reliable [[baseball statistics]] for all players were not widely available, so Topps actually compiled the information itself from published [[box score (baseball)|box scores]]. While baseball cards themselves had been around for years, including statistics was a relative novelty that fascinated many collectors. Those who played with baseball cards could study the numbers and use them as the basis for comparing players, trading cards with friends, or playing imaginary baseball games. It also had some pedagogical benefit by encouraging youngsters to take an interest in the underlying [[mathematics]].

The cards originally had one line for statistics from the most recent year (i.e. the 1951 season for cards in the 1952 set) and another with the player's lifetime totals. Bowman promptly imitated this by putting statistics on its own cards where it had previously only had biographical information. For the first time in 1957, Topps put full year-by-year statistics for the player's entire career on the back of the card. Over the next few years, Topps alternated between this format and merely showing the past season plus career totals. The practice of showing complete career statistics became permanent in 1963, except for one year, 1971, when Topps sacrificed the full statistics in order to put a player photo on the back of the card as well.
