Well - when I walked by, there were a number of people at his booth. Unlike some diehard bodybuilders, there are various mainstream fans who want Lou Ferrigno's autographs and pictures. That is his choice to charge what he wants for them. What I don't agree with is his refusal to take a picture with someone who doesn't want to buy a picture.
Yup, big Lou started all that. He looks at it like this: he's in the biz of selling pictures. If fans come up and take their own pic of him for free, they don't buy the pics he's selling. Back in the era he is from, pros made money selling pictures at all the shows and expos and many of them adopted Lou's tenet of business. Now most of the autographs are free to fans as a condition of an athlete's endorsement contract. Lou is still selling pics because he is still under contract with , not AMI, but with Joe Weider. He probably sold 150 photos over the weekend. That's an extra 3 grand in cash for Louie to take home. But, he still pays to produce the copies, so it is not all profit. Whatever it is, it is still worth it to Louie, and enough of his fans support him to keep him coming back. If Louie makes it to 80 and bodybuilding is also still around, he will still show up at the Olympia and the ASC to sell his pics.
