Is It Type?!

Source

I always find it interesting to look at different posters, book covers, etc.  I ran into this poster, which was created by Lennart Wolfert Grafisch.  You can check out the poster on his website here.  I think it's so creative because it uses different letters, punctuation, etc. to create the regular letterforms.  Trying to determine what typeface they used for the punctuation in order to create this piece is very hard, since they warped many of the numbers to fit the letterform (ex. the 7 creating the question mark).  If it were me, I would say the because it's readable, has the same x-height and is consistent, it's a typeface.  One could argue differently.  It's a very clever design, but my only complaint is the e's should've been more cleverly written.  Definitely a typeface!
