The article presents the postcards as a source of knowledge about the social reality for a sociologist. The first part contains a description of postcards, the discussion of visual studies and the theoretical justification of postcards' status as a data.

What we see on the postcards and then read - explains the second part of the article in which I empirically examine the usefulness of this type of sources, analyzing the photographic presentation of the city on one hand, and contents appearing on greeting postcards on the other.
