Reverse side of postcards

There is only one thing that makes a picture to be a postcard: it is its thickness of paper. A postcards should be thick enough to be mailed with no envelope. Because of this no envelope requirement postcards are called open letters in Russian ([otkrytoye pismo] or [otkrytka] for short).

When in French they are called carte postale the same was as in English. I also noticed that on some old European postcards they wrote "postcard" on several languages.

On the other hand to distinguish a postcard form just a a picture on a thick card-stock you may want to use the reverse side to put some information about the image or the company. Traditionally postcards also have some lines to make writing address easier.

Here are some examples of the reverse sides of the postcards.
