The PC-Cards include various postcards. These postcards range in size but most are in the 3 1/2″ x 5 1/2″ range. Backs also vary but, in general, feature either a divider line to separate the recipient’s address and message or are without a divider line.
In addition to these cataloged issues, numerous postcards not recognized in the American Card Catalog exist. A list of those issues is being tracked below as ‘Various Uncatalogued Issues.’ However, profiles have not been developed for them due to the sheer volume of sets not listed in the American Card Catalog.
Baseball postcards really became popular in the early 1900s. A slew of generic issues, in particular, was produced from around 1905 to 1915. Even if they do not have specific dates printed on them, a time period can usually be established on used ones that have postmark dates. Those dates, however, should not be confused with the precise year of issue as they may not have been used until years later.
Postcards can be a gray area for card collectors. While many consider them to be baseball cards of a sort, some collectors ignore them entirely. Because of that, many of the generic baseball postcards (those depicting the sport but not featuring actual players) are often relatively inexpensive. That is particularly true in the case of postally-used postcards. Those are generally found with some wear and sometimes, due to mail travel, etc., significant damage. However, those that do feature real players and teams are highly desired and often valuable.
The popular Exhibit Postcards can be found below and also in their proper classification with the W-Cards.
