Sorry for the late feedback but our customer didn't answer earlier... They like the #28 most - but ask for an integration of their old road-sign - which you find here:
https://dl.dropboxusercontent.com/u/3520444/Schild.jpgCould you combine those two (I don't know how...) ... maybe instead of the
"ammer
amper
radweg"
in your logo you could paste the letters AAR
and underneath the logo you could insert
"Ammer-Amper-Radweg"
but both in their font?
