Sebastian Brant's Narrenschiff (The Ship of Fools) (http://mdz10.bib-bvb.de/~db/0001/bsb00012790/images/index.html?seite=1), a book of German poetry, translated into English on Project Guttenberg (http://www.gutenberg.org/ebooks/20179).
University of Houston has a page with translated titles and illustrations (http://info.lib.uh.edu/sca/digital/ship/toc.html)
Lots and lots and lots of woodcuts by Albrecht Dürer, amongst others. This is a great resource for German costumers. :)
