The PC-Cards include various postcards. While there are generally not many pre-war basketball cards out there, postcards are an exception to that.
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.
As you might expect, it is possible to find both unused postcards and also postcards that have messages and have been postmarked. Both are collected but postcards that have not been used are generally worth more.
It is notable that many basketball postcard issues actually feature women instead of men.
Postcards can be a gray area for card collectors. While many consider them to be cards of a sort, some collectors ignore them entirely. Because of that, many of the generic basketball 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.
Below is a list of known postcard sets that have basketball issues. In addition to those listed below, numerous other individual basketball postcards exist that are not part of sets. Some of these include collegiate players or individual generic subjects. Due to the large amount of those issues, they have not been included in this section.
