Vinyl Record, Tape, Compact Disk and MP3

I decided to use pure typography to combine Vinyl record, Tape, Compact Disk and MP3 into only one poster. The circle in the left is formed by the definition of Vinyl Record, the circle in the right is formed by a short definition of Compact Disk. Moreover, the line that is connect these two circles together represent the digitalization from analog to digital signal. Furthermore, together these elements create the form of the magnetic tape. 

Before coming to this poster, i tried many different pictures to create a posters but they did not work well. So i turned back to the beginning and tried to use another way and i chose typography. Actually, i haven't used typography in my works in the previous semesters because i believe that a picture worth than thousand words. However, this semester, when i did the research on David Carson and his works, i was surprised by his works by the powerful ways he used his typography that's why now i am doing the research on typography and i hope that one day i can use the power of typography in my designs.
