As mdchachi says above, the signatures on the flag were all written by the same person. In other words, it wasn't signed by 20-30 different people. It was written by one person. The ink in each signature is the same; same thickness, same stroke idiosyncrasies, etc. The presenter's name looks like it was written by a child. (It could be that the presenter was just someone with poor penmanship, but it is highly unlikely. It feels like every signature is written poorly - as if the writer has no calligraphic training or familiarity.
