2021 was the 20th anniversary of the tragedies that transpired on September 11, 2001. Mark Whitford was a firefighter who perished on that fateful day. His family commissioned Sean to design a commemorative t-shirt. He had also designed a t-shirt for Mark in 2001.

This was a very personal project for Sean, as Mark was a dear friend of his from high school. He was honored to work on this projects for his old bud.
