Hmm free not really. At the beginning of the decade he was 60 a comic and around 100 for any other item signed. He is now 125 per signature usually at shows. The line is outrageous, he signs an item about every 3 seconds, and all you can do is say hi. You pick up your item and walk away. My guess is he signs a 1,000 plus items at an average show bringing in over a 100 grand an appearance in which the promoter probably agrees to an autograph guarantee they pay the difference of the agreed upon amount if he does not reach a certain dollar amount.
It is a terrible experience now in which he can't see what or where he is signing anymore nor can he here you. He is usually heavily guarded from each location usually riding a hoverround, but sometimes he walks. I don't think he is enjoying himself at this point and only doing these signings because others rely on him to make their income.
I love the man and think he should retire to enjoy the remaining days with his daughter, but probably he won't.
What I will warn people is that his signature is the most common signature in the world now based on he many things he signs at a show and the cost still does not deter the line. Lee probably has over 500,000 signatures in the market place and may have over 1,000,000 signatures out there.
