Jürgen,

Thanks for reading and commenting. I wanted the hairlines to be really thin, so they provide a hard contrast at display sizes while, at the same time, are almost unnoticeable at text sizes. I didn't want to make just another standard revival in several respects, so I expected the thin hairlines would contribute to set this revival apart from those of, say, Adobe and Linotype. Anyway, the topic doesn't seem to have generated too much enthusiasm ... Nonetheless, I have updated the specimen sheet linked to on the first post. Incidentally, the gif file now seems to be properly loadable within IE.

Thanks again.

Almost done! Lots of additions and refinements since the previous post, including a careful revision of each and every glyph. The font is finally an (almost) exact reproduction of the Klingspor original (with many convenient additions for modern OpenType use), providing vast improvements over the current Adobe/Linotype and other not-so-popular renditions.
Updated information and samples available at alterlittera.com.
Thanks in advance.
