Mr. Wolff is their staff designer. Although he didn't design the two logos that went up for a vote, he did design all the graphics the club released as part of that promotion. You can see some examples in this post: http://www.nycisblue.com/2014/03/time-to-vote.html
I hasten to add that he hasn't agreed to work with us. Only that he's agreed to talk to us. We'd be honored if he does indeed design our logo.
