As a public service, cyclecounters.org is pleased to host very high resolution images of the Charters of Freedom. These images were once available from the National Archives and Records Administration, but had to be removed from that site due to bandwidth constraints. At roughly 300dpi, these images are suitable for printing life-size reproductions. For smaller versions that are better suited to on-screen viewing, please visit the National Archives site at http://www.archives.gov/founding-docs
