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.
Postcards featuring various sports were extremely popular. This is particularly true between the dates of around 1905 – 1915.
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 postcards (those depicting the sport but not featuring actual athletes) are often relatively inexpensive.
Additionally, postally-used postcards are also more affordable. Those are generally found with some wear and sometimes, due to mail travel, etc., significant damage. However, those that do feature real athletes and teams are highly desired and often valuable.
Because of the large number of boxing postcard issues, only sets are presented here.
