Immermann Font

Google Translate says:

in Hamburg there is a road that the writer Karl Leberecht Immermann honors with her name. The German poet to be honored on street name, is nothing special. But what struck me more, was the special font in which the street sign is executed on the corner of Lessingstraße. Possibly originally all street signs in this district were designed in this document, but only this one has survived the times with some injuries and will probably soon be replaced by a new salvation, but designed just in normal font tag. So I modeled from the few letters a complete font. And as the name then offered also Immermann to, especially since other fonts absolutely carry the name of a person who has not much to do with the font, a very prominent example of this is the Arnold Böckliin font.
