Fasciculus:Franz Xaver Winterhalter BNF Gallica (cropped).jpg

Situs librariae huius operis theoretice incerta est quia, in regione originis, librae 100 annos post mortem auctoris durant, et tempus mortis auctoris (vel identitatis auctoris) ignoratur. Attamen tempus creationis operis ante 150 annos superatum fuit, et ideo rationabilis suppositio est librariae exspirasse (vide hic de communitate disceptationis). Obsecro, hoc noli utere si tempus mortis auctoris notum est. This work is in the public domain in the United States because it was published (or registered with the U.S. Copyright Office) before January 1, 1929.

This file has been identified as being free of known restrictions under copyright law, including all related and neighboring rights.

This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.
