Here are three collections of monochrome (b&w) scanned clip art. I do not have them available for preview. You can just download the zipped collections, and check them out for yourself. Click the links below, or the title headings, to download.
Scans-bw-300dpi
3883 PNG Images. This collection was gathered starting in the early 1990’s, while using Atari MegaSTe and TT computers. I scanned quite a few of the images myself, but others were gathered from collections posted on bulletin boards, and some come from old image collection CD’s. These are 300dpi (or less).
This collection contains everything. Animals, Designs, Scenery, Bible images, Transportation, etc. It also includes 300dpi versions of the “Horace Knowles” images made for the “RSV Bible.” Unfortunately, they are mixed in with the other images (although they are in categorized folders), but the style is distinct.
RSV-Bible–Horace-Knowles-600dpi
405 PNG Images. This collection was scanned a few years ago, when I got rid of the paper originals. These are higher resolution copies of just the RSV Bible images. For copyright on the Horace Knowles images, see details below.
Scans-bw-600dpi
180 PNG Images. This collection was scanned at the same time as the 600dpi Horace Knowles images, listed above. I was discarding my paper copies, so made one last effort to preserve them at higher resolution. This will contain some of what is in the 300 dpi bw scans, but not all. It is a much smaller collection, covering a range of topics. It is a small subset of the 300dpi collection, but scanned at higher resolution.
Regarding Copyrights
I get a few questions about this regularly. Here is what I know. Some of these scans I made myself. Others were taken from bulletin boards, CD collections, etc. This was from the early 1990’s, on an Atari computer. In those days, copyright was not such a hot issue as now. I expect most of the sources these came from do not exist today, or are not commercially active.
Some of the Bible pictures, I later found, came from Horace Knowles, who was commissioned by the British Bible Society to illustrate the New English Bible in the 1950’s. These illustrations were used in a few other versions as well, even up until 1995. Their copyright statement is here. I believe you can use these images for commercial work, but please read their statement carefully.
I don’t think you would have a problem using the others commercially, but cannot guarantee it. Caveat Emptor: “Let the Buyer Beware!” To this day, NOBODY has ever written to me claiming that such and such an image was theirs, and “could you please take it down.” Still…it could happen. So use them at your own risk.
I believe you are always safe if you use them “for educational use,” at least in the USA, under the “fair use” clause of the copyright laws. But I’m not a lawyer.
