Reproductions are intended for personal use, study, research or classroom teaching. Any fair use, as defined by copyright law (http://www.copyright.gov/fls/fl102.html), is acceptable.

Copyright of photographs and images may be difficult to determine. In many instances PNCA is not the rights holder under copyright law. Therefore, it is unlikely that we will be able to grant permission for publication, exhibition, or reproduction; nor can we guarantee the image is in the public domain.

Users must assume full responsibility for questions of potential copyright violation in their use of the image.
