This was a clever illusion that was set up in many of the tourist hangouts (with a bucket for donations). The guy on the bottom appears to be holding up a big metal post as effortlessly as a coffee cup. There is nothing between his sleeve and his lap to hold up the weight. Balanced on the top of the post is a second man in a mediation pose. He appears to be light as a feather. Both are real men occasionally moving slightly or looking around at the passers by. They would sit there for probably more than an hour.
