How to apply for an internship in an advertising agency

This was my way to introduce myself to my few favorite advertising agencies: A one page letter and envelope that contained all personal information and that was holding my work inside. As soon as the letter was opened, the work could be spreaded around the table. I was lucky that Scholz&Friends liked the idea and accepted me as an intern for 6 months in the time from 11/2009 till 05/2010.
