To the uploader:

1. Please add a detailed non-free use rationale for each article the image is used in, which must also declare compliance with the other parts of the non-free content criteria, as well as the source of the work and copyright information.
2. For example non-free use rationales, see Wikipedia:Use rationale examples.
3. Template:Non-free use rationale may be helpful for stating the rationale.
4. This tag is not a sufficient claim of fair use.

To patrollers and administrators: If this image has an appropriate rationale please append |image has rationale=yes as a parameter to the license template.

I (— Matt Crypto) feel it is covered by the U.S. fair use laws because:

1. The image is used for educational purposes only in a non-profit encyclopedia.
2. The image is no larger and of no higher quality than is necessary for the illustration of an article (that is, so the text on the postcard can be read).
3. The use of the image on Wikipedia is not expected to decrease the value of the copyright.
4. Its inclusion in the article adds significantly to the article because it shows how the subject of this article is commemorated in Poland.
