Poster for Seth Godin seminar

I've been a fan and reader of Seth Godin's for over 3 years. 
When he announced he was going on the road - a different city every month - 
Boston being the first - I volunteered to help. I ended up being part of the core organizing group - 
an amazing experience and I ended up designing all of the graphics for the event. 
This was the poster - it was also used for newspaper ads. 
The same graphics were used for the Wash DC seminar.
