My buddy came up with this.  He found it a some flea market.  A reliable source tells me it’s from the 80s.  WQUT and a certain fizzy drink maker’s local distributor had this balloon for events around the area.  I was told that, maybe, 250 of these were made, so there’s a whole bunch of them still…wait for it…floating around. (faint laughter off)

It’s got a pin-and-butterfly-clasp on the back. No maker name or mark.
