Identifying a German official (?) signature - Rome 1943

Morning.
Having trouble locating information on this bureau that issued this certificate in 1943 and the signature for the issuing German official...

The agency is identified as the Recruiting Office for Italian Workers of the Supreme Commander South.

Such Werbebüros for foreign laborers were set up in many places in occupied or Nazi-influenced territories, but I have no detailed information on their structure. The seal stamp is that of the German embassy in Rome; so apparantly, that office was subordinate/attached to the embassy.

The signature looks like "Franz Holtbecker" to me.

Thank you!
May you have a happy and healthy 2016!
