ملف:To Kill a Mockingbird (1963 US theatrical poster).jpg

English: 1963, per the copyright notice. Note that the film itself premiered December 25, 1962. While the poster appears to have been published following the premiere, the images seen on the poster are not taken directly from the film itself. Gregory Peck is shown in color while the film is in black-and-white, and it is almost certain that the image of Peck was derived from a photo rather than a still from the film itself; for example, compare a similar promotional photo showing Peck in front of a window (third row, left, with Mary Badham). Similar imagery of Peck in front of a window had also been disclosed by the film's pre-release trailer, which is in the public domain.

English: Scan via Heritage Auctions. Cropped from original image.

English: "Copyright © 1963 by Universal Pictures Co., Inc."

English: The poster included a valid copyright notice, seen at bottom left. However, the copyright for the artwork was not renewed, as was required by American copyright law to extend/maintain protection for works published 1963 or earlier. See the Copyright Catalog (1978 to present). In order to maintain copyright protection, the poster would have had to be renewed 28 years after publication. Because it was not renewed, copyright lapsed at that time. Note that the poster art is a distinct work from the film it represents and had to be renewed separately.
