One was created by me in May 2001, using my personal judgement about the proportions. The other was created in May 2003, using the official artwork as submitted to the Trademark Office (in 1969) as a template. It is not an exact match for the official artwork, but is much closer than the older version. Files with the ".ai" extension are in Adobe Illustrator 9 format. They are resolution-independent drawings, and may be scaled to any size without loss of crispness. If you have access to Illustrator, that is the best way to create a logo in the size you need. The large .gif files are very large bitmaps. If you don't have access to Illustrator but do have image editing tools, you should be able to create a high-quality logo by scaling one of these images. The file logo150sky.gif is the logo as it usually appears on the home page on http://www.amsat.org. It has a sky-blue background (#E0FFFF) and has been anti-aliased to that background color for crispness. It won't look right on any other background color without some work. If you need help creating a modified version of the AMSAT logo for some AMSAT-sponsored purpose, I may be able to assist you. Contact me by email.
