"One big cookie"

I don't remember exactly when the World's Largest Cookie (according to the sign that accompanied it) was on display in front in the CAB Building, but at some point in the 1970s it was propped up as a vertical exhibit. We walked by and said, "Boy, that is one big cookie." And then forgot about it as soon as it was out of sight. I'm sure someone has made a bigger cookie since then.
