More Clues About Qana?

Powerline posts about a giant poster of Dr. Rice apparently produced within hours of Qana.

What seems odd about this is that the banner was unfurled within hours after the Qana attack took place. The building where the civilians died was bombed on Sunday morning, and the demonstration took place during daylight hours, later the same day. I have no idea what kind of facility it takes to produce a 30-foot-high banner like this one. It is obviously professionally done. It would be interesting to know where this banner was produced; who designed and paid for it; and how its production was expedited so that it was ready for use, on the street, within hours after the event being protested. For example, was the image of Rice produced in advance, awaiting a pretext for its use, with only the script added at the last minute? I've often been curious about the logistics of pro-terrorist demonstrations, and this seems like an especially curious example.
