Since this 1935 reprint seems to have been a 100% truthful facsimile reproduction of the 1849 original (the image even shows the year 1849 as the publication date), I don't think it would be copyrightable in its own right. <a href="https://en.wikipedia.org/wiki/User:Lupo" class="extiw" title="en:User:Lupo">Lupo</a> 07:48, 20 March 2006 (UTC)
